Abstract :
We report removal of in-band amplified spontaneous emission (ASE) noise in a 10-Gbit/s noise-loaded RZ signal using a dispersion-imbalanced loop mirror. The resulting receiver sensitivity is improved from -37.0 dBm to -37.7 dBm. The loop mirror bias dependence of sensitivity is also investigated, and the optimal bias point is found to be where the transmission decreases with increasing input power.
