Physical origin of higher-order soliton fission in nanophotonic semiconductor waveguides
Charles Ciret, Simon-Pierre Gorza, Chad Husko +3
Supercontinuum generation in Kerr media has become a staple of nonlinear optics. It has been celebrated for advancing the understanding of soliton propagation as well as its many a…
Silicon nanowire based exclusive-OR gate using nonlinear optics for 40Gb/s DPSK signals
F. Li, T. D. Vo, C. Husko +7
We demonstrate an all-optical XOR logic function for 40Gb/s differential phase-shift keyed (DPSK) data signals in the C-band, based on four-wave mixing (FWM) in a silicon nanowire.…
Giant anomalous self-steepening in photonic crystal waveguides
Chad Husko, Pierre Colman
Self-steepening of optical pulses arises due the dispersive contribution of the Kerr nonlinearity. In typical structures this response is on the order of a few femtose…
Nonlinear silicon photonics analyzed with the moment method
Simon Lefrancois, Chad Husko, Andrea Blanco-Redondo +1
We apply the moment method to nonlinear pulse propagation in silicon waveguides in the presence of two-photon absorption, free-carrier dispersion and free-carrier absorption. The e…
Phase sensitive amplification in silicon photonic crystal waveguides
Yanbing, Zhang, Chad Husko +5
We experimentally demonstrate phase sensitive amplification (PSA) in a silicon photonic crystal waveguide based on pump-degenerate four-wave mixing. An 11 dB phase extinction ratio…
Multi-photon absorption limits to heralded single photon sources
Chad A. Husko, Alex S. Clark, Matthew J. Collins +7
Single photons are of paramount importance to future quantum technologies, including quantum communication and computation. Nonlinear photonic devices using parametric processes of…
