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…
Measuring intensity correlations of a THz quantum cascade laser around its threshold at sub-cycle timescales
Ileana Cristina Benea Chelmus, Christopher Bonzon, Curdin Maissen +3
The quantum nature of photonic systems is reflected in the photon statistics of the light they emit. Therefore, the development of quantum optics tools with single photon sensitivi…
THz ultrastrong light-matter coupling
Giacomo Scalari, Curdin Maissen, Sara Cibella +5
Cavity photon resonators with ultrastrong light-matter interactions are attracting interest both in semiconductor and superconducting systems displaying the capability to manipulat…
A quantum cascade phonon-polariton laser
Keita Ohtani, Camille Ndebeka-Bandou, Lorenzo Bosco +2
We report a laser that coherently emits phonon-polaritons, quasi-particles arising from the coupling between photons and transverse optical phonons. The gain is provided by an inte…
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…
