Abstract:
We present and experimentally demonstrate a new method to generate optical carrier suppressed-differential phase-shift keying (OCSDPSK) modulation format in radio over fiber (RoF) systems. In our scheme, a single dual-parallel Mach-Zehnder modulator (DPMZM) is used to produce OCS-DPSK signal based on amplitude shift keying (ASK) to DPSK format conversion by suppressing the spectral tones of an OCS-ASK signal.

This process is given by the generation rate G and is efficient due to the conservation of momentum between the valence band maximum and conduction band minimum.
