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…
Single-mode instability in standing-wave lasers: The quantum cascade laser as a self-pumped parametric oscillator
Tobias S. Mansuripur, Camille Vernet, Paul Chevalier +13
We report the observation of a clear single-mode instability threshold in continuous-wave Fabry-Perot quantum cascade lasers (QCLs). The instability is characterized by the appeara…
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…
Fresnel reflection from a cavity with net roundtrip gain
Tobias S. Mansuripur, Masud Mansuripur
A planewave incident on an active etalon with net roundtrip gain may be expected to diverge in field amplitude, yet Maxwell's equations admit only a convergent solution. By examini…
