3.5 Thz Quantum Cascade Laser at 70 K as Local Oscillator

3.5 Thz Quantum Cascade Laser at 70 K as Local Oscillator

We report a set of measurements to demonstrate a new type of surface emitting distributed feedback (DFB) quantum cascade laser (QCL) operated at 3.5 THz as a local oscillator by pumping a superconducting hot-electron bolometer (HEB) mixer. Based on the Bragg gratings incorporated into the waveguide,...
