현재 표준 파장 분할 다중화(WDM) 전송 시스템의 전송 용량을 늘리는 비용 효율적인 방법 중 하나는 C 대역 이외의 파장 대역을 사용하여 다중 대역으로 전송하는 것입니다. 우리는 넓은 파장 범위의 신호를 동시에 처리할 수 있는 파장 변환을 이용한 다중 대역 시스템 개념을 제안했습니다. 전광 파장 변환은 12파장 혼합을 통해 C 대역 WDM 신호를 고도 비선형 광섬유(HNLF)의 다른 대역으로 변환하는 데 사용할 수 있으며 C 대역만 사용하여 C 대역 이외의 신호를 포함한 여러 WDM 신호를 동시에 전송할 수 있습니다. -밴드 트랜시버. HNLF 이외의 다양한 비선형 도파관 재료에 대한 파장 변환이 보고되었습니다. 이러한 비선형 재료에서 우리는 분산 맞춤형 SOI(silicon-on-insulator) 도파관에 의한 광대역 전송 가능성을 발견했습니다. CMOS 공정은 정확도가 높아 양산 시 색분산 변동을 줄일 수 있을 것으로 기대된다. SOI 기반 도파관을 이용한 파장 변환의 폭을 연구하는 첫 번째 단계로 양쪽 끝에 에지 커플러가 제공되는 분산 맞춤형 12 스트립 도파관을 설계 및 제작했습니다. 96개의 도파관은 각각 서로 다른 폭과 길이를 가지며 렌즈형 섬유 또는 렌즈를 통해 섬유에 연결됩니다. 각 도파관을 특성화하기 위해 조정 가능한 광원을 펌프로 사용하고 변조되지 않은 3채널 C 대역 WDM 테스트 신호를 사용하여 펌프-프로브 실험 설정을 구성했습니다. 이 설정을 사용하여 삽입 손실, 입력 전력 의존성, 변환 대역폭 및 변환 효율성을 평가합니다. C밴드 테스트 신호가 100nm 이상에서 90dB 변환 대역폭을 갖는 동일한 실리콘 도파관을 사용하여 S밴드와 L밴드로 변환되었음을 확인했습니다. 또한, 도파관 길이를 단축하여 C-to-S 변환에 대해 최소 XNUMXnm의 증가된 설계 공차가 확인되었습니다. 비선형 도파관을 이용한 파장변환기는 다중대역 WDM 전송 시스템을 향상시키기에 충분히 넓은 변환 대역폭을 가짐을 확인하였다.

Abstract: One of cost-effective ways to increase the transmission capacity of current standard wavelength division multiplexing (WDM) transmission systems is to use a wavelength band other than the C-band to transmit in multi-band. We proposed the concept of multi-band system using wavelength conversion, which can simultaneously process signals over a wide wavelength range. All-optical wavelength conversion could be used to convert C-band WDM signals into other bands in a highly nonlinear fiber (HNLF) by four-wave mixing and allow to simultaneously transmit multiple WDM signals including other than the C-band, with only C-band transceivers. Wavelength conversion has been reported for various nonlinear waveguide materials other than HNLF. In such nonlinear materials, we noticed the possibility of wideband transmission by dispersion-tailored silicon-on-insulator (SOI) waveguides. Based on the CMOS process has high accuracy, it is expected that the chromatic dispersion fluctuation could be reduced in mass production. As a first step in the investigation of the broadness of wavelength conversion using SOI-based waveguides, we designed and fabricated dispersion-tailored 12 strip waveguides provided with an edge coupler at both ends. Each of the 12 waveguides having different widths and lengths and is connected to fibers via lensed fibers or by lenses. In order to characterize each waveguide, the pump-probe experimental setup was constructed using a tunable light source as pump and an unmodulated 96-ch C-band WDM test signal. Using this setup, we evaluate insertion loss, input power dependence, conversion bandwidth and conversion efficiency. We confirmed C-band test signal was converted to the S-band and the L-band using the same silicon waveguide with 3dB conversion bandwidth over 100-nm. Furthermore, an increased design tolerance of at least 90nm was confirmed for C-to-S conversion by shortening the waveguide length. It is confirmed that the wavelength converters using the nonlinear waveguide has sufficiently wide conversion bandwidth to enhance the multi-band WDM transmission system.
