Pilot-carrier based linewidth-tolerant 8PSK self-homodyne using only one modulator

Abstract

Linewidth-tolerant 8PSK self-homodyne modulation/demodulation using a DFB-LD with a linewidth of 30 MHz and only one modulator, based on a polarization-multiplexed pilot-carrier technique at 10 Gsymbol/s and even at 1 Gsymbol/s were demonstrated. (2 pages)
