Title: LIGHT GUIDE BODY, OPTICAL MODULE, AND METHOD FOR ADJUSTING OPTICAL AXIS OF OPTICAL PATH
Abstract:
The present invention is a light guide body for adjusting the optical axis of an optical path, the light guide body characterized by comprising a silicon single crystal having an extinction ratio of at least 30 dB. In particular, the present invention is a light guide body in which only one side surface of the light guide body is joined and fixed to a base. The present invention is also an optical module characterized by being provided with the abovementioned light guide body installed so that the installation angle thereof is adjusted to adjust the optical axis of an optical path between components. The present invention is also a method for adjusting the optical axis of an optical path, characterized by comprising adjusting the optical axis of an optical path between components by adjusting the installation angle of the abovementioned light guide body. A light guide body can thereby be provided whereby polarization characteristics are not adversely affected and the optical axis of an optical path can easily be adjusted. An optical module and a method for adjusting the optical axis of an optical path which use such a light guide body can also thereby be provided.
