초록

본 논문에서는 하나의 얇은 반파장판(half-wave plate)을 이용하여 광섬유-평면도파로 결합기(fiber-to-planar waveguide coupler)의 편광 의존성을 줄이기 위한 방법이 제안되었고 실험적으로 검증 되었다. 소자의 편광의존성 제거 원리를 설명하였고 제조과정을 기술하였다. 실험 결과는 소자의 공진 파장이 입력광의 편광상태에 독립적임을 보였다.

Abstract

In this paper, a method to eliminate the polarization dependent properties of fiber-to-planar waveguide couplers using a thin half-waveplate is proposed and demonstrated. The operation principle of the device is explained and the fabrication technology is presented. It is experimentally shown that the resonance wavelengths of the device are independent of the polarization state of input light
