Abstract :
We report demonstration of four-wave mixing based mid-span optical phase conjugation (OPC) in short dispersion engineered slow-light chalcogenide and silicon photonic crystal waveguides for dispersion compensation of 4 ps, 40 Gb/s return to zero pseudorandom signals transmission through an 2 km of standard optical fiber link. We take into account the impact of two photon absorption, free carrier absorption, free carrier dispersion, and repetition rate effects in our numerical simulations. We achieve conversion efficiency of -28.26 and -19.68 dB between idler and probe in Si and chalcogenide OPC using a CW pump with the power of 100 mW.
