Claims

[Scope of utility model registration request]

A built-in optical branching section consisting of two media with different refractive indexes using a variable refractive index crystal as at least one of the media, a refractive index control section for the crystal, and the optical branching section and the refractive index control section. The present invention is characterized by comprising a case and an optical connector attached to the case and having optical axes aligned with each of the incident light, reflected light, and transmitted light at a predetermined portion of the optical branching section. Optical splitter.
