Congratulations to Alex Spott and colleagues for a postdeadline paper at the 2017 IEEE International Photonics Conference on the first Interband Cascade Laser on Silicon.
We demonstrate the first interband cascade lasers heterogeneously integrated with silicon waveguides. The 3.6 μm wavelength lasers operate in pulsed mode at room temperature, with threshold currents as low as 394 mA.
