Electro-optic modulation using asymmetric Fabry-Perot laser diode amplifiers.
(1994)
We report the use of laser diode amplifiers, whose facets have unequal mirror reflectivities, as
asymmetric Fabry-Perot modulators. Due to the presence of optical gain in these devices we
observe modulation of reflected ...
All optical timing extraction with frequency division using a twin section laser diode.
(1993)
All-optical timing extraction from a coded line signal
with division of the extracted clock frequency is demonstrated
using a single twin-section self-pulsating laser diode.
Either the bit-rate clock or a submultiple ...
All optical, high contrast absorptive modulation in an asymmetric Fabry-Perot etalon
(American Institute of Physics, 1991)
We report a 27:l switching contrast ratio with 2.5 mW of power in an asymmetric Fabry-
Perot Ctalon. The modulation is achieved by optical saturation of the excitonic
absorption profile of a 95 A GaAs/AlGaAs multiple ...
Demonstration of high-brightness-mode propagation in a compound waveguide structure
(American Institute of Physics, 1999)
We demonstrate the existence of an unusual and useful high-brightness guided mode of a multimode
AlGaAs/GaAs heterostructure compound slab waveguide. This mode has a narrow near-field single
lobe confined to the low-index ...
The influence of the unlocked characteristics of a self-pulsating laser diode on synchronization
(1993)
All-optical synchronization and timing extraction
based on self-pulsating twin section lasers has been demonstrated.
We investigate the variation of the unlocked full-widthat-
half-maximum of the fundamental of the RF ...
Quasi-two-dimensional exciton in ZnSe/ZnMgSSe single quantum well
(American Physical Society, 1995)
We have studied the quasi-two-dimensional exciton in ZnSe/ZnxMg1 ? xSySe1 ? y (x=0.85, y=0.21) single quantum wells (SQWs) by photoluminescence and photoluminescence excitation spectroscopy. Self-consistent calculations ...
All-optical clock distribution with synchronous frequency division and multiplication
(1992)
A master optical clock from a mode locked laser is distributed
to two slave twin section lasers. One slave laser divides
the optical modulation frequency by 2, the other slave laser
multiplies the frequency by 2. It is ...
Growth and characterization of an epitaxially grown ZnSSe/MnZnSSe distributed Bragg reflector
(1995)
A Bragg reflector consisting of a 25-period MnZnSSe/ZnSSE Bragg stack is reported. The II?VI
semiconductor structure was grown by molecular beam epitaxy on a GaAs ~100! epilayer. Structural
characterization of the Bragg ...
Strain effect on the optical nonlinearity in an InGaAs/GaAs asymmetric Fabry-Perot modulator.
(American Physical Society, 1993)
The effect of strain on the optical nonlinearities and operation of an all-optical asymmetric
Fabry-Perot italon is investigated. A high reflectivity modulation of 60% is reported with a
contrast ratio of 12.2:1 and ...
Effect of temperature on self-pulsation in narrow stripe, gain-guided, compact disk laser diodes
(IEEE, 1998)
There is an ongoing strong interest in the development
of red self-pulsating lasers for data
storage compact disk (CD) applications.? Of
particular importance in this mass-market application
is that the laser diode ...
