Refining the Physical Model of External Radiation Affecting the Parameters of an Optical Waveguide

摘要

The influence of external optical radiation (EOR) on the parameters of an anisotropic single-mode optical waveguide (ASOW) is considered using a three-layer model. It is shown that the thermodiffusion time constants for the waveguide heating and cooling are ～10 and ～950 s, respectively; i.e., the considered system shows a sort of bistable state for the rate of variation of the optical waveguide temperature.
