Compact gas sensor using silicon-on-insulator loop-terminated Mach–Zehnder interferometer

RS El Shamy, MA Swillam, MM ElRayany, A Sultan… - Photonics, 2021 - mdpi.com
In this paper, we propose a compact optical gas sensor based on the widespread silicon-on-
insulator (SOI) technology, operating in the near-infrared (NIR) region around the 1.55 µm …

Optimization of silicon nitride waveguide platform for on-chip virus detection

RS El Shamy, MA Swillam, X Li - Sensors, 2022 - mdpi.com
This work presents a rigorous and generic sensitivity analysis of silicon nitride on silicon
