Paper Abstract

High detection sensitivity and large multi-user interference rejection are key requirements to accommodate a higher number of users in an optical coherent CDMA system. In this work, we propose efficient coherent homodyne receiver system configurations, as well as, demonstrate experimentally the performance of coherent homodyne pulse detection using a synchronized modelocked semiconductor laser system. We present the significant improvement of coherent gain and signal-to-noise ratio of the NRZ ASK format modulated PRBS data detection compared with direct detection.
