About Professor B P Pal
Professor
Bishnu Pal was born on Dec 3rd 1948 in Shillong India and is
currently Professor of Physics and Dean of Engineering at Mahindra
University’s École Centrale School of Engineering (earlier known as
Mahindra École Centrale or MEC in short) in Hyderabad India. Before
joining MEC established in 2014 in collaboration with École
Centrale Paris (now CentraleSuperlec) of France, he was a Professor
of Physics for over 24 years (and as a Physics faculty member for
about 34 years) at the Indian Institute of Technology Delhi, where
he served as the Chairperson of the Physics Department (September
2008-December 2011) and also of the Computer Services Center
(September 2002-August 2005). He was deeply involved in introducing
and developing the highly sought-after interdisciplinary M. Tech.
program on Optoelectronics and Optical Communication in 1980 at IIT
Delhi. Two of his research papers – one (co-authored with Arun
Kumar and Ajoy Ghatak) published in 1980 in Electronics Letters on
effect of an axial refractive index dip in a single-mode fiber on
the estimation of zero dispersion wavelength in it and another
(co-authored with A. Barh, G P Agrawal, B M A Rahman, and R K
Varshney) on the generation of THz in a specialty optical fiber in
published in 2015 in Optics Letters were reprinted in the IEE book
Progress in Optical Communication Vol. II ed by P J B Clarricoats
(1983), and in the e-book Newest Updates in Physical Science
Research Vol 4 ed by Jelena Purenovic, B P International London
(2021), respectively. Furthermore, two of his authored/co-authored
chapters from his edited book Guided Wave Optical Components and
Devices - Basics, Technology and Applications (Academic Press,
2006) were reprinted in the book The Optical Communications
reference (eds DeCusatis and Kaminow, Elsevier, 2010). He has
edited 4 books published by Elsevier/Academic Press, John Wiley/New
Age Publishers, Intech, and Viva publishers. Open access e-book
Frontiers in Guided Wave Optics and Optoelectronics (2010) edited
by him and published by Intech London has been downloaded over
140,000 times to date. He has also contributed over 15 chapters –
all by invitation in various books. Prof Pal has extensively
contributed to sponsored research and industrial consultancy and
especially several international collaborative research projects
that involved UK, USA, Russia, France, Malaysia and Hong Kong. His
recent areas of research have been microstructured specialty fibers
for mid-IR and THz photonics, silicon photonics, and meta
materials. His research career broadly covered design of
application-specific specialty optical fibers like dispersion
tailored fibers with low sensitivity to nonlinear optical effects,
fibers for inherently gain flattened fiber amplifiers, large mode
area fibers and fibers for DWDM transmission, all-fiber components
and devices with focus on design, technology, and characterization
including side-polished fiber half-coupler-based gain flattening
filters for optical fiber amplifiers, fused fiber couplers, and
wavelength interleavers as branching components for optical
communication networks, designs of 1D-microstructured optical
fibers like Bragg fibers for supercontinuum light, optical fiber
sensors, guided wave components and sensors based on silicon
photonics, and Anderson type localization of light in disordered
optical waveguide lattices.

About Guest Editor
Partha
Roy Chaudhuri is Professor of Physics at Indian Institute of
Technology Kharagpur, working in the area of Fiber and Integrated
Optics and Experimental Photonics. In 2000, he did his Ph D from
the Fiber Optics Group of Indian Institute of Technology Delhi.
During the Ph D research, his major contribution had been
technology development of a host of fused fiber coupler-based
all-fiber branching components required in an optical communication
network. It included process simulation of the tapered fiber fusion
process in the form of a rigorous theoretical model, complete
design of a menu-driven computer-controlled automated fabrication
rig, necessary electronics as well as electromechanical hardware
and associated software for fabricating these components with
state-of-the-art specifications. He then pursued postdoctoral
research at the Kyoto Institute of Technology, Japan, as a Japanese
Government Fellow, where he pursued research on various optical
waveguides, MMI couplers and components. During this postdoctoral
research, he came up with a new algorithm related to mode-solving
of any arbitrary refractive index profile waveguide based on a
Finite Difference Mode Convergence recipe, which he and his
graduate students extensively used in his research on fiber optics
and photonic crystal waveguides.
In 2002, he joined the Institute for Communications Research
at National University of Singapore, Singapore and pursued
experimental research with photonic crystal fibers and components.
In particular, he spearheaded projects on designing photonic
crystal waveguides/fibers with tailored high-birefringence and
dispersion properties and successfully realized some of these novel
designed PCFs through collaboration with Beijing Glass Research
Institute in China. His expertise on various efficient design
algorithms that rely on Finite Difference Method (FDM), Boundary
Element Method (BEM), and Perturbed Field Correction Analysis have
greatly facilitated modeling of fabricated waveguides and
components thereof to successfully interpret various experimental
results. Most of these works were reported in relevant
research journals.
In 2004, he joined the Faculty of Physics at IIT Kharagpur
where he is currently a Professor of Physics actively involved in
teaching and research. During 2004-2012, as incharge of the Optical
Division of the Central Research Facility which housed a fiber
drawing facility, he executed several R&D projects by drawing
custom-designed specialty optical Fibers. He has successfully
carried out (as PI and Co-PI) several Sponsored Research projects
funded by Government Agencies namely, DST, DRDO, BRNS, MHRD with
industry (IMPRINT) that led to deleverables, development of
technical Know-hows, copyrights and Patent applications. He is
involved with collaboration research with institues in India and
abroad. To date he has supervised (including ongoing Ph D theses)
12 Ph D theses and more than 35 MTech. and M Sc dissertations. He
is an author/coauthor of more than ninety research papers and
contributed invited chapters in six books. His NPTEL course on
Modern Optics has received wide appreciation of researchers from
India and abroad. He is Life Fellow of Opt Soc of India
(OSI), Institute of Electronics and Telecommunication Engineers
(IETE) and Life Member of Indian Science Congress Association
(ISCA), Member of OSA, the Optical Society of America, KIT
International Exchange Club. His current research interests are in
the area of microstructured optical fibers/photonic crystal
waveguides and devices for passive, and active/ and (active and
nonlinear) nonlinear applications and development of fiber optic
sensors for detection of weak elelctric and magnetic fields.
Recently he has joined Asian J Phys as one of the
Editors.
