Research and R&D contributions made by Prof. Bishnu Pal:

Prof Pal's research involved analysis, innovative design and realization of a diverse spectrum of application-specific specialty optical fibers and fiber amplifiers, technology development of all-fiber branching components for optical networks having potential applications in optical telecommunication, fiber optic sensors, and more recently on mid-IR photonics and THz photonics, and Anderson localization of light in disordered optical waveguides.

  • Prof Pal has contributed to analysis, design, and realization of dispersion compensating fibers (DCF) that find extensive use in any long distance optical communication system. His collaborative work with his French collaborators on this [J-L. Auguste, R. Jindal, J-M. Blondy, M. Clapeau, J. Marcou, B. Dussardier, G. Monnom, D. B. Ostrowsky, B. P. PAL, and K. Thyagarajan, -1800 ps/(nm.km) Chromatic Dispersion at 1.55 micrometer in a Dual Concentric Core Fiber, Electron. Letts., vol. 36, pp. 1689-1691 (2000)], which was the then a world record (received extensive citations over 100 times); the other related invited paper [J-L. Auguste, R. Jindal, J-M. Blondy, M. Clapeau, J. Marcou, B. Dussardier, G. Monnom, K. Thyagarajan, and B. P. PAL, Conception, Realization, and Characterization of a Dispersion Compensating Fiber, Opt. Fib. Tech. vol. 8, pp. 89-105 (2002)] has also received over 80 times citations. He is co-author of a US patent No. 6,650,812 B2, 2003 entitled Design of a small residual dispersion fiber along with a matching DCF on a related topic. Indo-French Science Council had rated his Indo-French collaborative project sponsored by IFCPAR/CEFIPRA on this topic as "Excellent".
  • His co-authored research paper entitled "Effect of refractive index dip on the zero total dispersion wavelengths in single-mode fibers" [B. P. PAL A. Kumar, and A. K. Ghatak, Electronics Letters, vol. 16, pp. 505-507, (1980)] got reprinted in the book: Progress in Optical Communication Vol. II, Ed. By PJB Clarricoats, IEE Press, Stevenage, UK (1982)]. This book contains a collection of select papers, which were considered to have contributed to the growth of Optical Communication in the early 1980s.
  • In recent times, his research involved a significant effort on the contemporary field of microstructured optical fibers (MOF). Prediction made by his team for generating supercontinuum light from a Bragg fiber kind of MOF in 2006 [B. P. PAL, S. Dasgupta, M. R. Shenoy, and A. Sysoliatin, Supercontinuum generation in a Bragg fiber: Design and Analysis, Optoelectron. Letts. vol. 2, pp. 342-344 (2006)] was demonstrated experimentally for the first time in his co-authored paper [H. T. Bookey, S. Dasgupta, N. Bezwada, B. P. PAL, A. Sysoliatin, J. McCarthy, M. Salganskii, V. Khopin, and A. K. Kar, Experimental demonstration of spectral broadening in all-solid silica Bragg fiber, Opt. Exp. vol. 17, No. 19, pp. 17130-17135 (2009)]. Super continuum light is well known to be an excellent source for carrying out optical coherence tomography (OCT) analysis of biological samples besides its potential use as a broadband source in high capacity DWDM fiber optical communication.
  • Prof Pal's team had designed an air-core dispersion compensating Bragg fiber [S. Dasgupta, B. P. PAL, and M. R. Shenoy, Design of a Dispersion Compensating Bragg Fiber with ultra- high Figure of merit, Opt. Letts., vol. 30, No. 15, pp. 1917-1919 (2005) that got reprinted in Virtual Journal of Nanoscale Sc. and Tech. of AIP, July 25, 2005 issue], was cited by US Navy as one of the three references in a Call for Projects for high power Laser Delivery. To date this paper has received over 45 times citations. He had also designed an air-core Bragg fiber for potential applications in metro optical networks with a dispersion spectrum almost identical to that of silica-based conventional fiber earlier marketed by the Company AlcaLucent (France) with added benefit of ultra-low transmission loss [B. P. PAL, S. Dasgupta, and M. R. Shenoy, Bragg Fiber Design for Transparent Metro Networks, Opt. Exp., vol. 13, pp. 621-626 (2005)]; this paper was accepted by Opt. Exp. journal within a week of its submission in January 2005.
  • Prof Pal's team had proposed introduction of a certain amount of chirp in the periodic cladding of Bragg reflection waveguides and later in Bragg fibers for bandgap engineering to widen the bandgap of such fibers and waveguides and reported it for the first time at the mega conference ICMAT in Singapore in the summer of 2007 and subsequently published [B. P. PAL, S. Ghosh, R. K. Varshney, S. Dasgupta, and A. Ghatak, Loss and dispersion tailoring in 1D photonic band gap Bragg reflection waveguides: finite chirped claddings as a design tool, Opt. Quant. Electron. vol. 39, pp. 983-993, (2007); and later extended to fibers in collaboration with a French colleague [S. Ghosh, R. K. Varshney, B. P. PAL, and G. Monnom, A Bragg-like Chirped clad all-solid microstructured optical fiber with ultra-wide bandwidth for short pulse delivery and pulse reshaping, Opt. Quant. Electron. vol. 42, pp. 1-14 (2010)].
  • An inherent gain-flattened erbium doped fiber amplifier was designed and realized by Prof Pal with his Ph.D. student and co-researchers from CGCRI Kolkata and LPMC, University of Nice France having potential applications in metro optical networks [B. Nagaraju, M. C. Paul, M. Pal, A. Pal, R. K. Varshney, B. P. PAL, S. K. Bhadra, G. Monnom, and B. Dussardier, Design and fabrication of an intrinsically gain flattened Erbium doped fiber amplifier, Opt. Commn. vol. 282, pp. 2335-2338 (2009)].
  • Prof. Pal was one of the few firsts to initiate research on fiber optic sensors in India. One of his co-authored papers on a tapered multimode fiber-based refractometer was reported as early as in 1984 [A. Kumar, T. V. B. Subrahmanyam, A. D. Sharma, K. Thyagarajan, B. P. PAL, and I. C. Goyal, A Novel Refractometer using a Tapered Optical Fiber, Electron. Lett. vol. 20, pp: 534-535 (1984)], which has until now received over 60 citations. In a relatively recent successfully concluded project sponsored by the Board of Research in Nuclear Science (BRNS) of the Bhabha Atomic Research Center (BARC), Prof. Pal's team had designed and developed an optrode for remote excitation and collection of weak fluorescence from a highly corrosive industrial/nuclear environment, which has been recognized by BARC as an indigenous important import substitution contribution.
  • Under a Technology Development Mission mode project funded by Ministry of Human Resource Development of the Govt of India in late 1990s he led the team @ IIT Delhi to develop in-house the complete technology platform for flame-fusion of fibers to realize a wide variety of fused fiber coupler-based components for optical networks [B. P. PAL, P. Roy Chaudhuri, and M. R. Shenoy, Fabrication and Modeling of Fused Biconical Tapered Fiber coupler Components, Fib. Int. Opt., vol. 22, pp. 97-118 (2003)]. It was the 3rd most cited paper from that journal during the period 2003 - 2005. Till now it has received over 55 citations. Prof Pal had also led design methodology and in-house development of the technology for experimental realization of all-fiber wavelength interleaver type mux/ demux filters for DWDM systems based on unbalanced Mach Zhender interferometers through concatenation of fused fiber couplers [N. Kumar, M. R. Shenoy, and B. P. PAL, Flattop all-fiber wavelength interleaver for DWDM transmission: Design analysis, parameter optimization, fabrication and characterization recipe, Opt. Comm. vol. 281, pp. 5156-5164 (2008)]. Subsequently he had collaborated with Prof Pak Chu's group at City U Hong Kong to extend these concepts, which led to realization of polymer-based integrated optical wavelength interleavers and comb filters [IEEE Photon. Tech. Lett. vol. 17(12), pp. 2619-2621 (2005); Opt. Comm. vol. 267 (2), pp. 373-378 (2006); Opt. Comm. vol. 282, pp. 883-886 (2008)].
  • He was Consultant-in-Charge (through FITT, IITD) for in-house fabrication and supply of a set of tailor-made side-polished half couplers to an US company "Intelligent Fiber Optic Systems", Mountain View, Calif in the year 1998 from IIT Delhi. His team's related work on realization of gain flattening wavelength filters for erbium-doped fiber amplifiers was awarded the very first Photonics 2004 endowment prize as the "Best device oriented research paper from an Indian Laboratory" during the Indian Photonics community's flagship Photonics 2006 conference held at Hyderabad. Experimental demonstration of a more advanced version of this work in terms of unaffected performance of such a filter even under add/drop of standard DWDM signal channels in a DWDM network was reported by his team [R. K. Varshney, B. Nagarazu, A. Singh, B. P. PAL, and A. K. Kar, 2007, Design and Realization of an All-Fiber Broadband Tunable Gain Equalization Filter for DWDM Signals, Opt. Exp. vol. 15, No. 21, pp. 13519-13530 (2007)].
  • More recently he proposed & experimentally demonstrated (through collaboration with collaborators from Heriot-Watt University Edinburgh in UK under an UKIERI major project sponsored to him by the British Government) ultrafast laser inscripted disordered waveguides in glass as a new platform for studying statistical nature of the fundamental phenomenon of transverse localization of light in disordered waveguide lattices (similar to Anderson localization of electronic wave function) [S. Ghosh, N. D. Psaila, R. R. Thomson, B. P. PAL, R. K. Varshney, and A. K. Kar, 2012, Ultrafast laser inscribed waveguide lattice in glass for direct observation of transverse localization of light, Appl. Phys. Letts. vol. 100, 101102-101145 (2012)] and published several other related papers.
  • Very recently he has extensively researched on a variety of chalcogenide and soft-glass based specialty optical fiber designs for realizing broadband and narrow band fiber-based light sources for Mid-IR photonics, and supercontinuum generation. His co-authored paper A. Barh, S. Ghosh, G. P. Agrawal, R. K. Varshney, I. D. Aggarwal, and B. P. PAL, Design of an efficient mid-IR light source using chalcogenide holey fibers: a numerical study, J. Opt. (IOP, UK), vol. 15 035205 (2013) was selected by the Editorial Board of that journal for inclusion in the exclusive 'Highlights of 2013' collection of articles.
  • As the Principal Investigator he has significantly contributed to a recent strategic Indian Defence Research and Development Organization (DRDO) project on polarization maintaining fiber designs for subsequent fabrication by CSIR-CGCRI Kolkata, this design and realization has been judged by DRDO's RCI Laboratory in Hyderabad as a breakthrough indigenous critical component development for their fiber optic gyro programme.
  • As the Chief Consultant for a recently concluded consultancy project, Prof Pal and his team made important contributions to the design of fibers for "Fiber to the Home (FTTH)" applications for the mega-fiber manufacturer in India Sterlite Technologies Ltd Aurangabad.
  • About his independently authored comprehensive review on "Guided wave optics on silicon: Physics, Technology, and Status", which included his own research on ARROW waveguides for the prestigious series Progress in Optics, vol. XXXII (1993), Editor Prof. Emil Wolf wrote in his preface that Prof. Pal's article is "a subject of considerable current interest and is likely to influence the design and fabrication of various optical components for future use in this field of technology". As is now well known Silicon Photonics is an intensely pursued research area including companies like Intel in USA. Prof Pal had guest edited a special issue on Guided Wave Optics on Silicon for the journal Proc. IEE (UK) Part J: Optoelectronics as early as in 1996.
  • Prof. Pal has published over 120 research papers and reviews in reputed international journals and reported over 80 papers in peer reviewed International conferences of repute; delivered over 50 invited/ plenary/keynote talks at international conferences in India and abroad; Edited 4 books; 12 invited reviews in peer reviewed international journals and monographs; 1 each US and Indian patent; 15 book chapters (all by invitation), and has been adviser of 17 successful Ph.D. theses and over 75 Masters theses at IITD.
