Education
Bangladesh University of Engineering & Technology (BUET)
February 2011 – March 2016 BSc in Electrical & Electronic Engineering, DhakaDid my undergrad from BUET, concentrating on Electrical & Electronic Engineering. Had a lot of fun while doing my undergrad and got to meet some outstanding people there. My major was communication and minor was electronics. My undergraduate thesis was on Photonic Crystal Fibers, which led to three published IEEE research articles (see Publications below). The courses I enjoyed most were Digital Signal Processing, Optical Fiber Communication, Numerical Methods, Signals and Systems, Random Signal Processing, and Control Systems. Alongside the coursework, I spent a lot of that time teaching myself programming and software development, entirely outside the curriculum, simply because I was already hooked on building things. Chasing that curiosity instead of just the grades is what turned into the career I have today.
Rifles Public School & College
August 2008 – July 2010 HSC in Science, DhakaStudied my HSC here. That was a short period of 2 years that just went by in a flash! Met some friends though. And some generous teachers. My uncle was a lecturer back then that was really helpful.

Ultra-high nonlinear photonic crystal fiber with GeO2 doped core
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 applications can be achieved by tuning the global design parameters.
Highly GeO2 doped polarization maintaining PCF for dispersion compensation
In this paper a highly GeO2 doped single mode equiangular spiral 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
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.
