FIELD: integrated optics.
SUBSTANCE: invention relates to integral optics, namely to optical radiation dividers. Invention consists in the fact that in the heat-resistant integral-optical radiation divider, in the substrate, there is a row of integral-optical microlenses, each of which is made of N optical microlenses, at the output of which there is a focusing system, in the focus of which there is one channel waveguide. Such design of the integrated optical divider makes it possible to divide the optical radiation even when the temperature varies in a wide range and to direct it to the optical radiation receiver.
EFFECT: technical result of disclosed invention consists in improvement of reliability of optical radiation divider in conditions of temperature oscillations in wide range.
