Abstract

We propose and demonstrate a methodology for simultaneous amplification and noise mitigation of optical signals through an ultrafast FWM-based oversampling followed by lossless decimation. The proposed method is particularly useful for improving the detection accuracy of noise-dominated narrowband optical signals.
