We demonstrate phase-sensitive amplification in hydrogenated amorphous silicon photonic waveguides based on pump-degenerate four-wave mixing at continuous-wave (CW) operation, as well as at repetition rates of both 90 MHz and 10 GHz. At 90 MHz pulsed operation, an 11.7 dB phase-sensitive extinction ratio (ER) is achieved with a peak pump power of 1.6 W. At 10 GHz pulsed operation, a 6.6 dB phase-sensitive ER is achieved with a peak pump power of 0.5 W. At CW operation, a 1.6 dB ER is achieved with a pump power of 38 mW.
