Phase-Matching and Parametric Conversion for the Mid-Infrared in As2S3 Waveguides
As2S3 Mid-Infrared Phase-Matching Four-Wave Mixing
2013/1/30
We illustrate two As2S3 waveguide designs for four-wave mixing, which can generate 3.03 μm mid-infrared light from a 1.55 μm near-infrared signal source and a 2.05 μm pump source. Through simulations,...
Femtosecond Cascaded Second-Order Nonlinearities in Quasi-Phase-Matching Devices
Frequency conversions Cascaded second-order nonlinearities Optical solitons
2009/6/8
Cascaded processes of energy exchanges between optical beams via second-order nonlinearities lead to various phenomena, including Kerr-like nonlinear phase shifts and optical solitons. The cascading n...
