Design of mid-infrared nonlinear silicon–germanium waveguides for broadband/discrete-band wavelength conversion

D Lyu, Q Jin, S Gao - JOSA B, 2018 - opg.optica.org
A dispersion-engineered silicon–germanium (Si_0. 8Ge_0. 2) waveguide is designed for
mid-infrared (MIR) broadband or discrete-band wavelength conversion by using its …

Impact of third-order dispersion and three-photon absorption on mid-infrared time magnification via four-wave mixing in Si0.8Ge0.2 waveguides
