| Abstract(in English) | An optical isolator is composed of a couple of polarizers whose transmission axes make an angle of 45° with each other and a Faraday 45° rotator sandwiched by the polarisers. Hence, the insertion loss of an optical isolator significantly varies depending on the polarization angle of the input light. On the other hand, when an elliptically polarized light is launched into a quarter wave plate followed by a polarizer, the output light power is kept constant regardless of the principal axis direction of the input light when the birefringence axis of the quarter wave plate and the transmission axis of the polarizer makes an angle of 45°. Input polarization direction dependence of the insertion loss of an optical isolator is reduced from 17dB to 0.4 dB by attaching a quarter-wave plate in front of a conventional optical isolator. |
