Abstract
A 1000 nm wide supercontinuum, spanning from 1470 nm in
the telecom band to 2470 nm in the mid-infrared is demonstrated in a 800 nm x 220 nm 1 cm long hydrogenated amorphous silicon strip waveguide. The pump source was a picosecond Thulium doped fiber laser centered at 1950 nm. The real part of the nonlinear parameter of this waveguide at 1950 nm is measured to be 100±10 W-1 m-1, while the imaginary part of the
nonlinear parameter is measured to be 1.2±0.2 W-1 m-1. The supercontinuum is stable over a period of several hours, as the hydrogenated amorphous silicon waveguides do not degrade when exposed to the high power picosecond pulse train. Related Research Topics
