Broadband monolithic extractor for metal-metal waveguide based terahertz quantum cascade laser frequency combs

Markus Rösch, Ileana-Cristina Benea-Chelmus, Christopher Bonzon +4

We present a monolithic solution to extract efficiently light from terahertz quantum cascade lasers with metal-metal waveguides suitable for broadband frequency comb applications.…

Quantum Cascade Laser Frequency Combs

Jérôme Faist, Gustavo Villares, Giacomo Scalari +4

It was recently demonstrated that broadband quantum cascade lasers can operate as frequency combs. As such, they operate under direct electrical pumping at both mid-infrared and TH…
