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…
Localization landscape theory of disorder in semiconductors. III. Application to carrier transport and recombination in light emitting diodes
Chi-Kang Li, Marco Piccardo, Li-Shuo Lu +7
This paper introduces a novel method to account for quantum disorder effects into the classical drift-diffusion model of semiconductor transport through the localization landscape…
Localization landscape theory of disorder in semiconductors II: Urbach tails of disordered quantum well layers
Marco Piccardo, Chi-Kang Li, Yuh-Renn Wu +7
Urbach tails in semiconductors are often associated to effects of compositional disorder. The Urbach tail observed in InGaN alloy quantum wells of solar cells and LEDs by biased ph…
Localization landscape theory of disorder in semiconductors I: Theory and modeling
Marcel Filoche, Marco Piccardo, Yuh-Renn Wu +3
We present here a model of carrier distribution and transport in semiconductor alloys accounting for quantum localization effects in disordered materials. This model is based on th…
