摘要

利用反向脈衝光時鐘注入半導體光放大器實現全光式非歸零碼轉歸零碼的格式轉換。當外部注入的非歸零碼訊號，其消光比為7.13dB，經此格式轉換後，轉換後歸零碼訊號的消光比提升到13.6dB，量測到的誤碼率為10^(-12)，功率補償為－3.7dB。

By using a semiconductor optical amplifier backward injected with a dark-optical-comb pulse-train at 10 GHz, we demonstrate a 10Gbit/s all-optical non-return-to-zero (NRZ) to return-to-zero (RZ) format conversion of an incoming optical pseudorandom binary sequence (PRBS) data-stream. Without any pre-amplification on the degraded optical NRZ PRBS data, its extinction ratio is greatly improved from 7.13dB to 13.6dB after converting into a RZ PRBS data. To date, the converted RZ PRBS data exhibits a negative power penalty of ＞3.7 dB at a BER of 10^(-12) in comparison with the NRZ PRBS data.
