Mid infrared two-photon absorption in a room-temperature extended-wavelength InGaAs photodetector
Marco Piccardo, Noah A. Rubin, Lauren Meadowcroft +4
We investigate the nonlinear optical response of a commercial extended-wavelength InGaAs photodetector. Degenerate two-photon absorption in the mid-infrared range…
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…
