I started research on the topic of Design and Modeling of
Erbium-Doped Fiber Amplifier
for WDM and DWDM Fiber Optic
Communication System in 2004 and completed
in 2009. The research on
EDFA requires mostly physics of optical light propagation
( Maxwell Equations applied to cylindrical coordinates for mode
solution), doped material
characteristics (rare earth metal like Er 3+ doped fiber’s
absorptions, spontaneous
and stimulated emission rate
questions, evolution equations of signal, amplified
spontaneous emission and
absorption of pump signals), numerical methods
to solve coupled partial
differential equations (e.g. 4th order Runga-Kutta Methods),
optimization techniques
(Simple Genetic Algorithm, Multi-Objective Genetic Algorithms),
and the most important use of coding on C++, Matlab and later on
Java.
After completion of my
doctoral degree, I was exploring to write a project proposal
and in that, I wrote two project proposals: one as an extension of
my Ph.D. work
and a second one on
Behavioral modeling of Optical Devices using
VHDL-AMS. Unfortunately, these two projects could not get
sanctioned for
financial support, and meanwhile, I shifted from ISM Dhanbad to
NEHU, Shillong
on the acceptance of a higher post from Assistant to Associate
Professor in
the Department of
Electronics and Communication Engineering (ECE).
Thereafter, I thought to
write a research proposal on some new emerging areas of
research that should be able to utilize the skills, competency, and
strength
of available manpower in the department of ECE as well as not
deviating from
my core area of specialization i.e., Optical Communication and
compatible
with the courses that I
studied during my six years of engineering graduate
training (3 years diploma in ECE and 3 years in B.Tech. in ECE).
