Strained Si/SiGe heterostructure has attracted great attention recently for its application in high speed and optoelectronic devises. However, the basic parameters such as band alignment are still not so clear due to the complexity of the ban

Based on four-wave mixing (FWM) with an optical comb source (OCS), we experimentally demonstrate 26-way or 15-way wavelength multicasting of 10-Gb/s differential phase-shift keying (DPSK) data in a highly-nonlinear fiber (HNLF) or a silicon waveguide

We generate a 790-nm wide Mid-IR supercontinuum, spanning from 1.63 μm to 2.42 μm, in a hydrogenated amorphous silicon waveguide. The pump source is a 160-fs Thulium doped fiber laser centered at 1910 nm.

We demonstrate phase-sensitive amplification in hydrogenated amorphous silicon waveguides based on pump-degenerate four-wave mixing at 90 MHz and 10 GHz. An 11.7 dB (6.6 dB) phase-sensitive extinction ratio is achieved at 90 MHz (10 GHz).

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

We use pump-probe spectroscopy and continuous wave cross-phase and cross-amplitude modulation measurements to study the optical nonlinearity of a hydrogenated amorphous silicon (a-Si:H) nanowire waveguide, and we compare the results to those of a cry

We experimentally demonstrate frequency resolved optical gating (FROG) via four-wave mixing (FWM) in ultrahigh nonlinearity hydrogenated amorphous silicon waveguides. We demonstrate FROG characterization using a FWM architecture that mimics second ha

We utilize a coherent optical comb generator to accomplish source efficient wavelength multicasting via four wave mixing in both a highly nonlinear fiber and a silicon nanowaveguide. We demonstrate 23 multicast channels with error free operation at 1

We demonstrate for the first time optical parametric amplification operating at a GHz rate in near-IR using hydrogenated amorphous silicon waveguides. The strong gain at this repetition rate shows its potential for telecommunication applications.
