Detection of poisonous gases using single-slot microring resonator based sensor

A microring resonator based sensor is proposed to detect different poisonous gases, such as carbon monoxide, phosphine, and nitrogen dioxide. These gases are very dangerous in environment if the leakage concentration is high. The single slot microring resonator sensor is used for detection of hazardous gases. The sensor has been analyzed through finite-difference-time-domain method by varying the radii of microring resonator from 1.4 μm to 2.2 μm and refractive index of the analytes. Transmission of microring resonator is observed and detected the different poisonous gases.
