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…
