Room temperature terahertz semiconductor frequency comb

Terahertz frequency combs are highly desired for applications in precision measurements, sensing, spectroscopy and metrology. Here the authors demonstrate the room-temperature chip-based THz frequency comb using nonlinear frequency generation from a mid-infrared quantum cascade laser comb.

Quantum cascade lasers that emit more light than heat

A mid-infrared quantum cascade laser that emits more light than heat and features a high wall-plug efficiency of up to 53% when operated a temperature of 40 K is reported. The device utilizes a single-well injector design.
