Abstract

We report experimental measurements of optical loss and n₂ nonlinearity in two possible InP-based mid-IR waveguiding platforms with waveguide cores made of In_0.53Ga_0.47As and GaAs_0.51Sb_0.49, both lattice-matched and grown on InP. We report the first broadband (5-11 μm) characterization and optimization of optical losses within InP/InGaAs and InP/GaAsSb based waveguides with losses as low as 0.5 dB/cm at shorter wavelengths and 4-5 dB/cm at longer wavelengths of this wavelength range. In addition, we measure the values of Kerr nonlinearity in these waveguides to be approximately an order of magnitude higher than that reported for Si- and SiGe-based waveguides in mid-IR.
