PROBLEM TO BE SOLVED: To remarkably reduce mounting dimensions while keeping the conventional function as an optical circuit device, the required light resistance, reliability and manufacturing easiness in a polarized light synthesizer. SOLUTION: This polarized light synthesizer includes a lens assembly 110a-1 having a fixing member 111a-1 for fixedly disposing the ends of plural optical fibers 211, 221 capable of propagating different polarized component light and a lens 112-1 for converting polarized component light of plural kinds emitted from the respective optical fibers 211, 221 to a collimate beam, wherein the synthesizer further includes a double refraction member 120a-1 for polarizing and synthesizing polarized component light of plural kinds as the same optical axis by using a difference in refractive index characteristic between polarized component light of plural kinds emitted from the lens 112-1. |
