Photoluminescence spectra of GaAsSb.GaAs quantum wells grown by molecular beam epitaxy exhibit strong blue shifts of the emission peak with increasing excitation intensity, indicating a type II ban
We report both experimental and theoretical studies of the optical properties in KCI of a defect-associated In center whose sole previously identified optical transition was a strong band peaking a
Room temperature optical reflectance spectra will be presented for the insulating parent compounds of high T sub c superconductors, M sub 2 CuO sub 4 and M sub 2-x Sr sub x O sub 4 for M = Nd, Sm,
We present a comprehensive analysis of the optical constants of the two- dimensional dichalcogenide materials 2H- TaSe2 and 2H- NbSe2, in an attempt to address the physics of two- dimensional corre
Single quantum wells of GaInAs and GaInAsP isolated by 150angstroms thick InP barriers have been grown by gas source molecular beam epitaxy.
The optical and structural properties of wurtzite GaN nanowires containing zinc-blende GaN inclusions of different thicknesses are investigated.
Nonlinear optical pulse compression of picosecond pulses typically requires long lengths of optical fiber and multiple components Periodic structures, such as fiber Bragg gratings, are highly dispe
Using a flow apparatus the time dependence of 6s(2) (1)S(0)- 6s6p (1)P(1) (553.5nm) resonance fluorescence in atomic barium has been studied following switch-on of cw laser excitation.
We present the first observation of absorption quenching by electrical control of the carrier density in a single semiconductor quantum well used as conducting channel in a field transistor.
The principles of optical receiver design are reviewed, with an emphasis on the design of low-noise preamplifiers for high sensitivity.
