NUMERICAL CHARACTERISTICS OF THE POLARIMETRIC INTERFEROMETER MADE BY K-NA+ ION-EXCHANGE()

The paper presents numerical optimizing investigations of planar polar imetric interferometer made by K+-Na+ ion exchange in glass for sensor applications. Two cases are considered - phase modulation of guided l ight waves caused by refractive index changes of the waveguide cover f or applications of the polarimetric interferometer as refractometer or chemical sensor, and phase changes induced by nanometer movements of a dielectric layer separated from the waveguide by an air gap of the w idth below wavelength of light for using the polarimetric interferomet er as an acoustical transducer and pressure or displacement sensor.
