최근 초고속 광통신 시스템이 발달함에 따라, 광통신 시스템 및 초고속 광통신 시스템의 핵심 부품인 평면도파로형 분배기(Splitter) 및 결합기(Coupler), 파장분할 다중화소자(WDM), AWG(Arrayed Wave Guide) 필터와 같은 소자부품 수요가 급격히 늘고 있다. 그러나 이러한 소자를 생산하는 공정은 수공적인 방법에 의존하여 생산성 향상을 위한 자동화에 대한 요구가 시급하다 특히 소자(Devices)와 광섬유(Optical fiber) 사이의 광학적인 정렬(Alignment)과 접속(Attachment) 공정은 부품 성능 및 생산성 향상, 그리고 비용절감을 위한 가장 핵심적인 문제로 대두되고 있다.(중략)

In recent years, as the demands of VBNS(Very high speed Backbone Network Service) and VDSL(Very high-data rate Digital Subscriber Line) increase, the development of kernel parts of optical communication such as PLC(Planar Light Circuit), Coupler, WDM elements increase. The alignment and the attachment technology are very important to fabricate the optical elements for communication. In this paper, the mechanism of rotational stage, the contact sensing unit, and integrated control circuit for the optical alignment system are studied.

In recent years, as the optical Communication systems are developed, the demands of essential parts such as splitter, coupler, WDM, and AWG filter are grow rapidly. The fabrication process for them is not, however, automatic. On that reason, the automation is needed for the grow of productivity. The optical alignment and attach ment is the core process in fabrication. In this paper, the 6-axis rotary stage for multi-channel optical alignment system is developed and the dynamic characteristic of this system is studied.
