Light guide body, optical module, and optical path and optical axis adjustment method

Abstract

A light guide body for optical path and optical axis adjustment, the light guide body includes a silicon single crystal having an extinction ratio of 30 dB or more. The light guide body is a light guide body having one side surface alone joined and fixed to a base. An optical module including the light guide body installed at an installation angle adjusted for optical path and optical axis adjustment between components. An optical path and optical axis adjustment method including adjusting an installation angle of the light guide body to perform the optical path and optical axis adjustment between components. It is possible to provide the light guide body which does not adversely affect polarization characteristics and can easily perform the optical path and optical axis adjustment. It is possible to provide optical module and the optical path and optical axis adjustment method using such a light guide body.
