O esquema de multiplexação por divisão de comprimento de onda (WDM) é amplamente utilizado em redes fotônicas metro-core. Em uma rede WDM, a restrição de continuidade de comprimento de onda é empregada para simplesmente construir nós de retransmissão. Essa restrição reduz a eficiência de uso do comprimento de onda de cada link. Para melhorar o mesmo, um conversor de comprimento de onda totalmente óptico (AO-WC) tem atraído a atenção nos últimos anos. Em particular, um AO-WC é um dispositivo chave porque permite a conversão simultânea de múltiplos comprimentos de onda de luzes de sinalização para outros comprimentos de onda, independentemente do formato de modulação. No entanto, cada AO-WC requer a instalação de múltiplas fontes de laser com largura de banda estreita porque as luzes emitidas pelas fontes de laser são usadas como luzes de bomba quando os comprimentos de onda das luzes de sinal são convertidos pelo processo de mistura de quatro ondas (FWM). Para reduzir o número de fontes de laser, propomos um AO-WC com bombeamento remoto, no qual as fontes de laser das luzes da bomba são agregadas em vários nós de relé. Quando a solicitação para a conversão de comprimento de onda do nó de retransmissão sem a fonte de laser é transmitida, o nó de retransmissão com a fonte de laser transmite a luz da bomba através do link óptico. O esquema proposto permite a redução do número de fontes de laser nas luzes da bomba. Aqui analisamos a distorção da luz da bomba propagando-a através do link óptico. Também avaliamos o efeito do ruído em amplificadores ópticos e não linearidades em fibras ópticas usando simulações numéricas empregando os parâmetros representativos para uma rede WDM prática.

Abstract: Wavelength division multiplexing (WDM) scheme is used widely in photonic metro-core networks. In a WDM network, wavelength continuity constraint is employed to simply construct relay nodes. This constraint reduces the wavelength usage efficiency of each link. To improve the same, an all-optical wavelength converter (AO-WC) has been attracting attention in recent years. In particular, an AO-WC is a key device because it enables simultaneous conversion of multiple wavelengths of signal lights to other wavelengths, independent of the modulation format. However, each AO-WC requires installation of multiple laser sources with narrow bandwidth because the lights emitted by the laser sources are used as pump lights when the wavelengths of the signal lights are converted by the four-wave mixing (FWM) process. To reduce the number of laser sources, we propose a remote pumped AO-WC, in which the laser sources of the pump lights are aggregated into several relay nodes. When the request for the wavelength conversion from the relay node without the laser source is conveyed, the relay node with the laser source transmits the pump light through the optical link. The proposed scheme enables reduction in the number of laser sources of the pump lights. Herein we analyze the distortion of the pump light by propagating it through the optical link We also evaluate the effect of the noise in optical amplifiers and nonlinearities in optical fibers using numerical simulations employing the representative parameters for a practical WDM network.

AB - Wavelength division multiplexing (WDM) scheme is used widely in photonic metro-core networks. In a WDM network, wavelength continuity constraint is employed to simply construct relay nodes. This constraint reduces the wavelength usage efficiency of each link. To improve the same, an all-optical wavelength converter (AO-WC) has been attracting attention in recent years.
