Planar Optical Waveguide Sensor Structures with Grating Couplers

摘要

The paper presents optical planar waveguide sensor structures with grating couplers of groove density χ = 2400 g/mm. The waveguide films were obtained using sol-gel method, in which the grating couplers were fabricated by the embossing method. The results of theoretical analysis as well as the results of experimental research have been presented.
