Controlling Quantum Cascade Laser Optical Frequency Combs through Microwave Injection
Barbara Schneider, Filippos Kapsalidis, Mathieu Bertrand +4
In this work, control over the precise state emitted by quantum cascade laser frequency combs through strong radio-frequency current modulation close to their repetition frequency…
Femtosecond pulses from a mid-infrared quantum cascade laser
Philipp Täschler, Mathieu Bertrand, Barbara Schneider +5
The quantum cascade laser (QCL) has evolved to be a compact, powerful source of coherent mid-infrared (mid-IR) light. However, its fast gain dynamics strongly restricts the formati…
Ultra-low threshold lasing through phase front engineering via a metallic circular aperture
Zhixin Wang, Filippos Kapsalidis, Ruijun Wang +2
Semiconductor lasers with ultra-low thresholds and minimal footprints are a topic of active research. Such devices require a combination of high quality factor laser cavities with…
