Silicon integration of mid-infrared (MIR) photonic devices promises to enable low-cost, compact sensing and detection capabilities that are compatible with existing silicon electronic technologies. Heterogeneous by bonding III-V wafers waveguides has been employed previously build integrated diode lasers for wavelengths from 1310 2010 nm. Recently, Fabry-Pérot Quantum Cascade Lasers on provided a 4800 nm light source applications. Distributed feedback (DFB) appealing many high-sensitivity chemical spectroscopic applications require single frequency, narrow-linewidth MIR source. While heterogeneously 1550 DFB have demonstrated introducing shallow surface grating waveguide within the active region, no laser reported date. Here we demonstrate quantum cascade silicon-on-nitride-on-insulator (SONOI) waveguides. These emit over 200 mW pulsed power at room temperature operate up 100 °C. Although output is not mode, nonetheless imposes wavelength selectivity 22 thermal tuning.
