Thermoelectrically cooled THz quantum cascade laser operating up to 210 K
Lorenzo Bosco, Martin Franckié, Giacomo Scalari +3
We present a \MF{terahertz} quantum cascade laser operating on a thermoelectric cooler up to a record-high temperature of 210.5 K. The active region design is based on only two qua…
An electrically pumped phonon-polariton laser
Keita Ohtani, Bo Meng, Martin Franckié +4
We report a device that provides coherent emission of phonon polaritons, a mixed state between photons and optical phonons in an ionic crystal. An electrically pumped GaInAs/AlInAs…
Two-well quantum cascade laser optimization by non-equilibrium Green's function modelling
M. Franckié, L. Bosco, M. Beck +5
We present a two-quantum well THz intersubband laser operating up to 192 K. The structure has been optimized with a non-equilibrium Green's function model. The result of this optim…
InP/InAsP Nanowire-based Spatially Separate Absorption and Multiplication Avalanche Photodetectors
Vishal Jain, Magnus Heurlin, Enrique Barrigon +11
Avalanche photodetectors (APDs) are key components in optical communication systems due to their increased photocurrent gain and short response time as compared to conventional pho…
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…
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…
