Abstract:
The operation of three types of waveguide refractometric sensors–interferometric Mach–Zehnder, interferometric two-mode, and grating waveguide—has been analyzed. The design features of these sensors with division into functional blocks have been considered. The overall dimensions of sensors based on chalcogenide glasses have been calculated to obtain the same detection limit for the gas analyzed medium.
Keywords:
refractometric sensor, input grating coupler, chalcogenide glass, detection limit, sensitivity.
