Room temperature surface emission on large-area photonic crystal quantum cascade lasers
Yong Liang, Zhixin Wang, Johanna Wolf +5
We design and fabricate large-area (1.1 mm 1.1 mm) photonic crystal quantum cascade lasers, enabling single-mode (wavelength 8.5 m) surface emission at room temp…
Coexisting frequency combs spaced by an octave in a monolithic quantum cascade laser
Andres Forrer, Markus Roesch, Matthew Singleton +3
Quantum cascade lasers are proving to be instrumental in the development of compact frequency comb sources at mid-infrared and terahertz frequencies. Here we demonstrate a heteroge…
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…
Magneto-transport controlled by Landau polariton states
Gian L. Paravicini-Bagliani, Felice Appugliese, Eli Richter +10
Hybrid excitations, called polaritons, emerge in systems with strong light-matter coupling. Usually, they dominate the linear and nonlinear optical properties with applications in…
Evidence of Linear Chirp in Mid-Infrared Quantum Cascade Lasers
Matthew Singleton, Pierre Jouy, Mattias Beck +1
We measure the inter-modal phase relation of a quantum cascade laser frequency comb operating at 8 um using a coherent beatnote spectroscopy. We find these phases to be reproducibl…
