Neste artigo, relatamos uma análise experimental e numérica da transmissão de pulso de Nyquist coerente de ultra-alta velocidade. Primeiro, descrevemos um compensador de dispersão de baixa não-linearidade para transmissão de pulso Nyquist coerente de ultra-alta velocidade; é composto por uma rede de Bragg de fibra chirped (CFBG) e um dispositivo de cristal líquido sobre silício (LCoS). Ao adotar CFBG em vez de fibra de dispersão inversa, a não linearidade em uma linha de transmissão de 160 km foi reduzida para mais da metade. Além disso, ao eliminar a flutuação do atraso de grupo do CFBG com um dispositivo LCoS, o atraso de grupo residual foi reduzido para apenas 1.42ps em uma largura de banda de 11nm. Então, usando a linha de transmissão com o recém-construído compensador de dispersão de baixa não linearidade, conseguimos melhorar o desempenho BER da transmissão de canal único de 15.3 Tbit/s-160 km em um terço em comparação com o de uma linha de transmissão convencional gerenciada por dispersão. e obteve uma eficiência espectral de 8.7 bits/s/Hz. Além disso, analisamos numericamente o desempenho do BER de sua transmissão de pulso Nyquist. Os resultados numéricos mostraram que o comprometimento não linear na linha de transmissão é o principal fator que limita o desempenho da transmissão em uma transmissão de pulso de Nyquist coerente, que se torna mais significativa em taxas de transmissão mais altas.

Abstract: In this paper, we report an experimental and numerical analysis of ultrahigh-speed coherent Nyquist pulse transmission. First, we describe a low-nonlinearity dispersion compensator for ultrahigh-speed coherent Nyquist pulse transmission; it is composed of a chirped fiber Bragg grating (CFBG) and a liquid crystal on silicon (LCoS) device. By adopting CFBG instead of inverse dispersion fiber, the nonlinearity in a 160km transmission line was more than halved. Furthermore, by eliminating the group delay fluctuation of the CFBG with an LCoS device, the residual group delay was reduced to as low as 1.42ps over an 11nm bandwidth. Then, by using the transmission line with the newly constructed low-nonlinearity dispersion compensator, we succeeded in improving the BER performance of single-channel 15.3Tbit/s-160km transmission by one-third compared with that of a conventional dispersion-managed transmission line and obtained a spectral efficiency of 8.7bit/s/Hz. Furthermore, we numerically analyzed the BER performance of its Nyquist pulse transmission. The numerical results showed that the nonlinear impairment in the transmission line is the main factor limiting the transmission performance in a coherent Nyquist pulse transmission, which becomes more significant at higher baud rates.
