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…
