Self-starting Harmonic Comb Emission in THz Quantum Cascade Lasers
Andres Forrer, Yongrui Wang, Mattias Beck +3
Harmonic comb state has proven to be emerging in quantum cascade lasers and promoted by an interplay between parametric gain and spatial hole burning. We report here on robust, pur…
Harmonic frequency combs in quantum cascade lasers: time-domain and frequency-domain theory
Yongrui Wang, Alexey Belyanin
Harmonic frequency combs, in which the lasing modes are separated by a period of tens of free spectral ranges from each other, have been recently discovered in quantum cascade lase…
Semiconductor ring laser frequency combs induced by phase turbulence
Marco Piccardo, Benedikt Schwarz, Dmitry Kazakov +10
Semiconductor ring lasers are miniaturized devices that operate on clockwise and counterclockwise modes. These modes are not coupled in the absence of intracavity reflectors, which…
Purcell enhancement of the parametric down-conversion in two-dimensional nonlinear materials
Mikhail Tokman, Zhongqu Long, Sultan AlMutairi +4
Ultracompact nonlinear optical devices utilizing two-dimensional (2D) materials and nanostructures are emerging as important elements of photonic circuits. Integration of the nonli…
Watt-level widely tunable single-mode emission by injection-locking of a multimode Fabry-Perot quantum cascade laser
Paul Chevalier, Marco Piccardo, Sajant Anand +7
Free-running Fabry-Perot lasers normally operate in a single-mode regime until the pumping current is increased beyond the single-mode instability threshold, above which they evolv…
Self-starting harmonic frequency comb generation in a quantum cascade laser
Dmitry Kazakov, Marco Piccardo, Yongrui Wang +7
Optical frequency combs establish a rigid phase-coherent link between microwave and optical domains and are emerging as high-precision tools in an increasing number of applications…
Active mode locking of quantum cascade lasers operating in external ring cavity
D. G. Revin, M. Hemingway, Y. Wang +2
Stable ultrashort light pulses and frequency combs generated by mode-locked lasers have many important applications including high-resolution spectroscopy, fast chemical detection…
