Numerical Study of a Dual-Mode Optical Sensor for Temperature and Refractive Index Sensing with Enhanced Temperature Range

Numerical Study of a Dual-Mode Optical Sensor for Temperature and Refractive Index Sensing with Enhanced Temperature Range

This study presents a photonic integrated optical sensor based on a dual-polarization microring resonator with angular gratings on a silicon-on-insulator (SOI) waveguide, enabling simultaneous and precise refractive index (RI) and temperature measurements. Due to the distinct energy distributions fo...
