Design of a Multimode Interferometer-Based Mid-Infrared Multispecies Gas Sensor
Original language description
A multimode interferometer beam splitter based on mid-infrared emitting chalcogenides waveguides is designed. This device multiplexes infrared light in two channels whose respective bands overlap either CO2 or CO absorption bands, respectively between 4.20-4.32 and 4.50-4.86 micrometer. Tolerances to variations from the optimum device design resulting from processing conditions (materials fabrication and sputtering, photolithography and dry etching) are assessed. In particular, the spectral transmission is investigated as a function of deposited film refractive index and multimode section dimensions (width and length) deviation from designed values.
