Education

Bangladesh University of Engineering & Technology (BUET), Dhaka — BSc in Electrical & Electronic Engineering

February 2011 - March 2016

Did my undergrad from BUET. Concentrating on Electrical & electronic Engineering. Had a lot of fun while doing my undergrad. Had the opportunity to meet some outstanding people there. My major was communication and minor was electronics. Not totally happy with my CGPA though! Could've done so much better. That's because I was pursuing so many things at the same time like developing programming and software development skills which was outside of my curriculum. People are not good at multi-tasking. Lesson learned indeed!

A nice photo challenge for you. See if you can find me in this picture!



Rifles Public School & College, Dhaka — HSC in Science

August 2008 - July 2010

Studied my HSC here. That was a short period of 2 year that just in a flash! Met some friends though. And some generous teachers. My uncle was a lecturer back then that was really helpful.

Publications

Ultra-high nonlinear photonic crystal fiber with GeO2 doped core

Publishing date: Feb 16, 2017

Publisher: IEEE Xplore Digital Library

This paper articulates our recent investigation on the properties of highly nonlinear photonic crystal fiber (HN-PCF) with concentrated GeO2 doped core using Finite Element method (FEM). The proposed PCF shows extremely high nonlinearity with very small effective mode area and convenient dispersion characteristics in telecommunication window. Suitable nearly zero dispersion profile at operating wavelength for nonlinear applicationscan be achieved by tuning the global design parameters.



Highly GeO2 doped polarization maintaining PCF for dispersion compensation

Publishing date: Feb 16, 2017

Publisher: IEEE Xplore Digital Library

In this paper a highly GeO2 doped single mode equiangular s piral photonic crystal fiber (HDES-PCF) is proposed to achieve high birefringence with extremely high negative dispersion, higher nonlinearity with low confinement loss for E+S+C+L+U band of interest. From the simulation results, large negative dispersion of -602.7803 ps/nm/km at 1.33 μm and -903.5316 ps/nm/km at 1.55 μm is achieved.



Low loss porous-core photonic crystal fiber for long-haul broadband THz transmission

Publishing date: Feb 16, 2017

Publisher: IEEE Xplore Digital Library

This paper presents a novel porous-core photonic crystal fiber (PCF) having extremely low material absorption loss at terahertz window suitable for THz transmission. Finite element method (FEM) is used to investigate the properties of the proposed PCF with a porous core surrounded by a compact cladding structure having hexagonal air holes.
