우리는 PD-SMZ(편파 식별 대칭 마하젠더) 전광 스위치의 초고속 및 고반복 기능을 실험적으로 시연합니다. 이 스위치는 원래 SMZ(대칭형 Mach-Zehnder) 전광 스위치와 마찬가지로 수동 InGaAsP 벌크 도파관에서 공진적으로 여기되는 매우 효율적이지만 천천히 완화되는 밴드 필링 효과를 기반으로 합니다. 느린 이완 효과를 상쇄하는 메커니즘을 사용함으로써 초고속 전환이 가능해졌습니다. 우리는 200fs의 스위칭 시간과 1.5Tbps의 역다중화를 달성하여 처음으로 1Tbps를 훨씬 넘는 광 역다중화에 SMZ 또는 PD-SMZ 전광 스위치의 적용 가능성을 보여줍니다. 스위칭 속도 외에 또 다른 중요한 문제인 고반복 성능도 10.5GHz 반복률의 제어 펄스를 사용하여 검증됩니다. 또한 제어 펄스 에너지를 더욱 줄이기 위해 반도체 광 증폭기에서 비선형성을 사용하는 방법에 대해서도 논의합니다.

Abstract: We experimentally demonstrate the ultrafast and high-repetition capabilities of a polarization-discriminating symmetric Mach-Zehnder (PD-SMZ) all-optical switch. This switch, as well as an original symmetric Mach-Zehnder (SMZ) all-optical switch, is based on a highly efficient but slowly relaxing band-filling effect that is resonantly excited in a passive InGaAsP bulk waveguide. By using a mechanism that cancels out the effect of the slow relaxation, ultrafast switching is attained. We achieve a switching time of 200 fs and demultiplexing of 1.5 Tbps, showing the applicability of the SMZ or PD-SMZ all-optical switches to optical demultiplexing of well over 1 Tbps for the first time. High-repetition capability, which is another important issue apart from the switching speed, is also verified by using control pulses at a repetition rate of 10.5 GHz. We also discuss the use of nonlinearity in a semiconductor optical amplifier to further reduce the control-pulse energy.
