Abstract
We propose hydrogenated amorphous silicon nanowires as a
platform for nonlinear optics in the telecommunication wavelength range.
Extraction of the nonlinear parameter of these photonic nanowires reveals a
figure of merit larger than 2. It is observed that the nonlinear optical
properties of these waveguides degrade with time, but that this degradation
can be reversed by annealing the samples. A four wave mixing conversion
efficiency of + 12 dB is demonstrated in a 320 Gbit/s serial optical
waveform data sampling experiment in a 4 mm long photonic nanowire.
