Observation of Nondegenerate Two-Photon Gain in GaAs
Matthew Reichert, Arthur L. Smirl, Greg Salamo +2
Two-photon lasers require materials with large two-photon gain (2PG) coefficients and low linear and nonlinear losses. Our previous demonstration of large enhancement of two-photon…
Third harmonic generation in graphene and few-layer graphite films
Nardeep Kumar, Jatinder Kumar, Chris Gerstenkorn +4
We observe optical third harmonic generation from graphene and few-layer graphite flakes produced by exfoliation. The emission scales with the cube of the intensity of the incident…
All-optical switching in planar semiconductor microcavities
S. Schumacher, N. H. Kwong, R. Binder +1
Using a microscopic many-particle theory, we propose all-optical switching in planar semiconductor microcavities where a weak beam switches a stronger signal. Based on four-wave-mi…
Ultrafast extrinsic spin-Hall currents
E. Ya. Sherman, Ali Najmaie, H. M. van Driel +2
We consider the possibility of ultrafast extrinsic spin-Hall currents, generated by skew scattering following the optical injection of charge or pure spin currents. We propose a ph…
Two-photon spin injection in semiconductors
R. D. R. Bhat, P. Nemec, Y. Kerachian +3
A comparison is made between the degree of spin polarization of electrons excited by one- and two-photon absorption of circularly polarized light in bulk zincblende semiconductors.…
