Abstract
Изобретение относитс к интегральной оптике. Цель изобретени упрощение способа измерени . Излучение ввод т через один торец, выво- д т через другой торец волновода. В процессе измерени интенсивности выходного излучени измен ют температуру волновода, что вызьшает изменение его оптической Длины. Это приводит к периодическому изменению пропускани плоского резонатора, образованного исследуемым волноводом и его торцами, и изменению интенсивности выходного излучени . По отношению минимальной интенсивности к максимальной вычисл ют затухание волновода.This invention relates to integrated optics. The purpose of the invention is to simplify the measurement method. The radiation is introduced through one end, outputted through the other end of the waveguide. In the process of measuring the intensity of the output radiation, the temperature of the waveguide is changed, which causes a change in its optical length. This leads to a periodic change in the transmission of a plane resonator formed by the waveguide under study and its ends, and a change in the intensity of the output radiation. The attenuation of the waveguide is calculated from the ratio of the minimum intensity to the maximum.
