Abstract

This work studies a variable optical attenuator using a reflective type liquid crystal cell for optical switches. The proposed architecture is capable of comprising a compact and low voltage driving variable optical attenuator. The usefulness of the proposed architecture is demonstrated by showing characterization of the liquid crystal cell, temperature effects, and response characteristics of the architecture.

본 논문은 광스위치등에 사용되는 가변 광감쇠기를 위해 반사형 액정셀을 채용한 광감쇠기 구조를 제안하고 특성을 검토한다. 본 제안의 가변 광감쇠기는 반사형구조로 소형화가 가능하고 저전압구동이 가능하다. 광통신용 파장에 적합한 액정셀의 설계방법, 주변온도에 따른 동작특성, 광감쇠기의 응답특성 등을 검토하여 본 제안 구조의 유용성을 검증한다.
