Abstract :
By exploiting non-degenerate four-wave mixing in highly nonlinear fibers assisted by two phase-modulated pumps, we report optical multicasted hexadecimal coding/decoding of 16-QAM. Constellation manipulation for a 10-Gbaud/s 16-QAM signal is demonstrated with OSNR penalties of <;2.4 dB for multicasted coding and <;1.6 dB for decoding.
