Керування світлопропусканням тришарових оптичних хвилеводів

Abstract

The study of a light transmission in the opticalwaveguide consisting ofa multimode lossless rod and thin dielectric lossyfilms of higherrefractive index as compared to the rod has been carried out. It has been shown that provision of the rod principle modes cutoff regime causes an increase ofthe sensor output powerwhile the surrounding mediummeasuring refractive index increases.
