Ultrafast reflectivity modulation in AlGaAs/InAlGaAs multiple quantum well photonic crystal waveguides
A. Z. Garcia-Deniz, P. Murzyn, A. M. Fox +6
We report an ultrafast optical tuning of the reflectivity of AlGaAs/InAlGaAs multiple quantum well photonic crystal waveguides using a reflection geometry, pump-probe technique.
Mirrored strain-balanced quantum well concentrator cells in the radiative limit
J. P. Connolly, M. F. Führer, D. C. Johnson +7
Strain-balanced Quantum Well Solar Cells (SB- QWSCs) are radiatively dominated at concentrator current levels. Incorporating back surface mirrors on the back of the doped substrate…
Fingerprints of spatial charge transfer in Quantum Cascade Lasers
R. Nelander, A. Wacker, M. F. Pereira +7
We show that mid infrared transmission spectroscopy of a quantum cascade laser provides clear cut information on changes in charge location at different bias. Theoretical simulatio…
Strain-Compensated AlInGaAs-GaAsP Superlattices for Highly-Polarized Electron Emission
A. V. Subashiev, L. G. Gerchikov, Yu. A. Mamaev +5
Spin-polarized electron emission from the first superlattice photocathodes developed with strain compensation is investigated. An opposite strain in the quantum well and barrier la…
