Abstract
Between a lens of a collimator and a retro-reflector as a total reflecting element, a prism, a polarizer, a Faraday rotator and a linear retarder are arranged in the order. The core/clad section serving as an input optical fiber of the collimator has its optical axis coincident with an optical axis of the lens. When the light exited the collimator reaches the retro-reflector, the outgoing light reflects deviated by a spacing Y, the returning light of which is refracted by the prism and incident on the core/clad serving as an output optical fiber of the collimator.
