Coherent Demodulation of Optical 8-Phase Shift-Keying Signals Using Homodyne Detection and Digital Signal Processing

Not Accessible

Abstract

We demonstrate coherent demodulation of optical 8-phase shift-keying signals for the first time. Since the carrier phase is estimated accurately through digital signal processing, the system performance is highly tolerant toward the carrier phase noise.
