摘要：

We demonstrate mid-infrared ring resonators fabricated in an In0.53Ga0.47As/InP materials platform operating at a wavelength of approximately 5.2 mu m with quality factors over 120 000. We also perform broadband characterization of optical losses in passive In0.53Ga0.47As/InP ridge waveguides in the 5-11 mu m wavelength range with waveguide losses ranging from below 0.5 dB/cm at shorter wavelengths to 4-5 dB/cm at longer wavelengths of this spectral range. Our results establish In0.53Ga0.47As/InP as a low-loss waveguiding platform for mid-infrared photonic integrated circuits that are fully integrable with InGaAs/AlInAs/InP quantum cascade lasers and detectors.& nbsp;(c) 2022 Author(s).
