Binary optical switch and programmable optical logic gate based on the integration of GaAs/AlGaAs surface-emitting lasers and heterojunction phototransistors
Metadata
Show full item recordAbstract
Optical switches based on GaAs/AlGaAs vertical-cavity surface-emitting lasers and heterojunction phototransistors are combined monolithically into new switching configurations that perform optical logic and spatial routing in a dynamically programmable manner. Using simple voltage control, many different logic and routing configurations, including AND and OR gates with variable fan-out, can be implemented using the same hardware.

Contrails of Small and Very Large Optical Depth
This work deals with two kinds of contrails. The first comprises a large number of optically thin contrails near the tropopause. They are mapped geographically using a lidar to obtain their height and a camera to obtain ... -
Simulation and Observations of Stratospheric Aerosols from the 2009 Sarychev Volcanic Eruption
We used a general circulation model of Earth's climate to conduct simulations of the 12-16 June 2009 eruption of Sarychev volcano (48.1°N, 153.2°E). The model simulates the formation and transport of the stratospheric ... -
Polyimide-planarized, vertical-cavity surface emitting lasers with 17.0 GHz bandwith
High speed, oxide-confined, polyimide-planarized 850 nm vertical cavity surface emitting lasers (VCSELs) exhibit – 3dB modulation bandwidths up to 17.0 GHz. The devices are fabricated using a reproducible, simple process ...
