Abstract :
We demonstrate a novel technique for suppressing the optical beat noise (OBN) which is key limitation in multiple access optical communication networks such as OCDMA. Using cross gain modulation induced amplitude mapping function (XGM-AMF) we drastically reduce the power penalty due to OBN. We experimentally show that dynamic power range for interference is improved by as large as 10-dB for a 1-dB power penalty limit compared to conventional photodetection techniques
