Abstract :
We propose and demonstrate optical hexadecimal coding/decoding of 16-QAM using degenerate four-wave mixing (FWM) in highly nonlinear fibers (HNLFs). Constellation manipulation for variable coding/decoding of a 10-Gbaud/s 16-QAM signal is implemented with an OSNR penalty of <;1.1 dB with CW pump and <;1.2 dB with phase-modulated pump Key.
