摘要

通过光纤参数放大器，我们展示了一种新的预放大方案，以提高10gb /s非归零开关键控(NRZ-OOK)格式的接收器灵敏度，该方案在光参数放大器(OPA)中采用信号和空转的双端叠加。我们在BER = 10 - 9时实现了- 40.5 dBm的接收机灵敏度。与单端接收机相比，接收机灵敏度可提高2 dB。

Receiver sensitivity improvement for NRZ-OOK signal by optical parametric amplifier-assisted detection

By using a fiber optical parametric amplifier, we demonstrate a novel pre-amplification scheme to improve receiver sensitivity for 10-Gb/s non-return-to-zero on-off keying (NRZ-OOK) format with dual-end superposition of signal and idler in the optical parametric amplifier (OPA). We achieve receiver sensitivity of −40.5 dBm at BER = 10−9. Compared to its single-end counterpart, the receiver sensitivity can be improved by 2 dB.
