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…
On-chip Dual-comb based on Quantum Cascade Laser Frequency Combs
Gustavo Villares, Johanna Wolf, Dmitry Kazakov +4
Dual-comb spectroscopy is emerging as one of the most appealing applications of mid-infrared frequency combs for high-resolution molecular spectroscopy, as it leverages on the uniq…
Dispersion engineering of Quantum Cascade Lasers frequency combs
Gustavo Villares, Sabine Riedi, Johanna Wolf +4
Quantum cascade lasers are compact sources capable of generating frequency combs. Yet key characteristics - such as optical bandwidth and power-per-mode distribution - have to be i…
Room Temperature Operation of a Buried Heterostructure Photonic Crystal Quantum Cascade Laser
R. Peretti, V. Liverini, J. M. Wolf +6
High power single mode quantum cascade lasers with a narrow far field are important for several applications including surgery or military countermeasure. Existing technologies suf…
