초록
본 논문에서는 반도체 광 증폭기(Semiconductor Optical Amplifier)의 교차 진폭 변조 현상을 이용하여 광 컴퓨팅이나 광통신에서 데이터의 패킷 교환, 데이터 리셋 혹은 추가나 제거에 필수적인 전광 데이터 추출을 시뮬레이션하고 실험적으로 구현하였다. 전광 데이터 추출의 실험적 시뮬레이션에는 상용 프로그램인 VPI Tool을 사용하였으며 기본적으로 두 개의 반도체 광 증폭기(SOA)를 사용하여 AND 논리를 구성한 후 이를 이용하여 데이터를 추출하였다. 또한 높은 집적성과 효율로 고속으로 연산할수 있는 가능성을 확인하였다.
Abstract
All-optical data extraction, one of the key technologies for all-optical computing and optical communication to perform add-drop,packet switching, and data reset, etc., is experimentally demonstrated by using cross-gain modulation (XGM) of semiconductor optical amplifiers (SOAs). Also, all-optical data extraction based on numerical simulation is performed by using the VPI simulation tool. In this paper, the suggested optical system based on SOAs shows the potential for high speed, and highly integrable and low power optical data computing.
