Hot-exciton relaxation in CdxZn1-xTe/ZnTe multiple quantum wells
(1991)
We have observed the creation of hot excitons at high momentum in CdxZn1-xTe multiple quantum wells and subsequent relaxation by LO-phonon emission to give sharp luminescence lines superimposed on a broader background. The ...
Molecular beam epitaxy growth of MgZnSSe/ZnSSe Bragg mirrors controlled by in situ optical reflectometry.
(1995)
In situ optical reflectometry at the wavelength of 488 nm was employed to control the growth of
MgZnSSe/ZnSSe Bragg mirror stacks for the blue-green spectral region. 10- and 20-period layer
structures of MgZnSSe/ZnSSe ...
Carrier-density dependence of the photoluminescence lifetimes in ZnCdSe/ZnSSe quantum wells at room temperature
(1999)
Photoluminescence lifetimes have been measured at room temperature as a function of carrier
density in ZnCdSe/ZnSSe quantum wells. We show that, at low carrier density (53109?5
31010 cm22), nonradiative recombination ...
Carrier lifetimes in strained InGaAs/(Al)GaAs multiple quantum wells
(1993)
The etfect of strain, strain relief, and barrier design on the carrier lifetime in InGaAs/(Al)GaAs
multiple-quantum-well samples is investigated. Carriers lifetimes are measured in samples with
varying amount of strain, ...
Effect of Coulomb enhancement on optical gain in (Zn,Cd)Se/ZnSe multiple quantum wells
(American Physical Society, 1997)
The optical-gain spectra of a 40-? (Zn,Cd)Se/ZnSe multiple quantum well has been measured at various temperatures using a variable-stripe method. By comparison with a gain calculation including many-body effects, we have ...
All-optical synchronization of self-pulsating laser diodes
(1996)
We examine the behavior of self-pulsating laser diodes when injected with periodic optical signals.
We experimentally and theoretically investigate the phase difference between the injected optical
signal and the ...
All-optical synchronization and frequency division of mode-locked pulses
(1992)
We report all-optical synchronization and frequency
division of mode-locked input signals, using a selfpulsating
laser diode. The performance of mode-locked and
sinusoidal input signals are compared. Synchronization ...
Bistable self-electro-optic operation of strained In0.1Ga0.9As/GaAs asymmetric Fabry Perot modulators
(1991)
We report bistable operation of a strained-layer InGaAs/GaAs asymmetric Fabry-Perot
optical modulator configured as a self-electro-optic effect device (SEED) operating in reflection
mode. Bistable loops are observed from ...
An experimental and theoretical analysis of jitter in self-pulsating lasers synchronized to periodic electrical signals
(1996)
We investigate both experimentally and theoretically
the behavior of pulse jitter in compact disk (CD) self-pulsating
lasers that have been synchronized to an applied periodic electrical
signal. Our investigations reveal ...
Room-temperature exciton luminescence in II-VI quantum wells
(1991)
We observe free excitons in absorption and emission at room temperature in Cd0,2sZne.7sTe/
ZnTe multiple quantum wells. A large overlap between luminescence and absorption
peaks observed at 10 K is maintained up to room ...
