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.…
Ultra-broadband quantum cascade laser operating from 1.88 to 3.82 THz
Markus Rösch, Mattias Beck, Martin J. Süess +4
We report on a heterogeneous active region design for terahertz quantum cascade laser based frequency combs. Dynamic range, spectral bandwidth as well as output power have been sig…
Short pulse generation and mode control of broadband terahertz quantum cascade lasers
Dominic Bachmann, Markus Rösch, Martin J. Süess +5
We report on a waveguide engineering technique that enables the generation of a bandwidth up to 1 THz and record ultra-short pulse length of 2.5 ps in injection seeded terahertz qu…
On-chip, self-detected THz dual-comb spectrometer
Markus Rösch, Giacomo Scalari, Gustavo Villares +3
We present a directly generated on-chip dual-comb source at THz frequencies. The multi-heterodyne beating signal of two free-running THz quantum cascade laser frequency combs is me…
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…
Octave-spanning semiconductor laser
Markus Rösch, Giacomo Scalari, Mattias Beck +1
We present here a semiconductor injection laser operating in continuous wave with an emission covering more than one octave in frequency, and displaying homogeneous power distribut…
