Picosecond pulse shaping in a semiconductor-coated D-shaped fiber.
Amorphous films of alpha-SiC:H and alpha-Si:H were deposited upon the flat surfaces of D-shaped fibers. Interaction of light with the semiconductor films occurred through evanescent coupling. Pulse shaping on a picosecond time scale was observed in 3.5-cm-long fibers with optical powers of <10 W, enhancing the effective nonlinearity by a factor of 10(3) .
