Hybrid Si-GST Polarization-Insensitive Dynamically Tunable Bifocal Metalens Operating at 1.55-m Wavelength
Dipika Rani Nath, Sadid Muneer, Sajid Muhaimin Choudhury
Metasurfaces have become a cornerstone of flat-optics, enabling precise control over light propagation through nanoengineered materials. Dynamic and reconfigurable metalenses are k…
Harnessing Topological Valley-Hall States in Photonic Crystals for Label-Free Refractive-Index Discrimination of Cancer Cell Lines
Junayet Hossain, Sajid Muhaimin Choudhury, Mohammed Imamul Hassan Bhuiyan
Topological photonic crystals (TPhCs) are the photonic analogs of topological insulators, inspired by the quantum Hall effect and its variants, including the integer, spin, and val…
Design of Dual-Band Plasmonic Absorber for Biomedical Sensing and Environmental Monitoring
Ayon Sarker, Sajid Muhaimin Choudhury
This study introduces a dual-band plasmonic absorber designed for simultaneous sensing applications in the near-infrared (NIR) and mid-infrared (MIR) regions. The absorber, compose…
Efficiency Enhancement of c-Si/TiO Heterojunction Thin Film Solar Cell Using Hybrid Metal-Dielectric Nanostructures
Soikot Sarkar, Sajid Muhaimin Choudhury
The hybrid metal-dielectric nanostructures (HMDN) are promising candidates to address the ohmic loss by conventional nanostructures in photovoltaic applications by strong confineme…
Lithium Niobate Photonic Topological Insulator-based Multi-Wavelength Optical Demultiplexer with Piezoelectric Switch-Off
Prithu Mahmud, Kaniz Fatema Supti, Sajid Muhaimin Choudhury
Photonic topological insulators provide unidirectional, robust, wavelength-selective transport of light at an interface while keeping it insulated at the bulk of the material. The…
Synergizing Deep Learning and Phase Change Materials for Four-state Broadband Multifunctional Metasurfaces in the Visible Range
Md. Ehsanul Karim, Md. Redwanul Karim, Sajid Muhaimin Choudhury
In this article, we report, for the first time, broadband multifunctional metasurfaces with more than four distinct functionalities. The constituent meta-atoms combine two differen…
TiN-GST-TiN All-Optical Reflection Modulator for 2 m Waveband Reaching 85% Efficiency
Md Asif Hossain Bhuiyan, Shamima Akter Mitu, Sajid Muhaimin Choudhury
In this study, we present an all-optical reflection modulator for 2m communication band exploiting a nano-gear-array metasurface and a phase-change-material GeSbTe (…
T Grating on Nano-Cavity Array based Refractive Index Sensor
Yasir Fatha Abed, Md Asif Hossain Bhuiyan, Sajid Muhaimin Choudhury
We report a refractive index sensor comprising of unique T grating on top of periodic nano-cavities. The sensor has two resonant modes sensitive to different regions of the structu…
Plasmonic metamaterial based virus detection system: a review
Mohammad Muntasir Hassan, Farhan Sadik Sium, Fariba Islam +1
Our atmosphere is constantly changing and new pathogens are erupting now and then and the existing pathogens are mutating continuously. Some of these pathogens, such as SARS-CoV-2,…
