An Optical PSK-RF-signal Transmitter based on ASK-to-PSK Conversion and Self-heterodyning

Abstract

An optical transmitter for generating phase-shift-keying (PSK) radio-frequency (RF)-signal is experimentally demonstrated, where a high-frequency RF-carrier is obtained by self-heterodyning and the PSK-modulation is achieved by the amplitude-shift-keying-to-PSK conversion in an integrated dual-parallel Mach-Zehnder modulator.
