테이퍼된 쿼츠 튜브를 이용한 1x3 PCF 커플러 제작 및 특성

In this paper, we proposed and demonstrated 1x3 type polymer clad fiber(PCF) coupler incorporating a tapered quartz tube which works optical combining and dividing region. A fabricated PCF coupler showed 4.6~5.3dB of insertion loss for optical combining and 5.2~5.9dB of insertion loss for optical spitting.
