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…
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…
