    ItemOpen Access
    Binary optical switch and programmable optical logic gate based on the integration of GaAs/AlGaAs surface-emitting lasers and heterojunction phototransistors
    (Colorado State University. Libraries, 1994) Vawter, G. A., author; Chalmers, S. A., author; Zolper, J. C., author; Lear, Kevin L., author; Zilko, John Leon, author; Adams, A. C., author; Leibenguth, Richard E., author; Cheng, Julian, author; Lu, Yin-Chen, author; Zhou, Ping, author; Lu, Bo, author; IEEE, publisher
    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.

    Reconfigurable binary optical routing switches with fan-out based on the integration of GaAs/AlGaAs surface-emitting lasers and heterojunction phototransistors
    (Colorado State University. Libraries, 1994) Vawter, G. A., author; Chalmers, S. A., author; Lear, Kevin L., author; Zolper, J. C., author; Zilko, John Leon, author; Adams, A. C., author; Leibenguth, Ronald E., author; Cheng, Julian, author; Lu, Yin-Chen, author; Lu, Bo, author; Zhou, Ping, author; IEEE, publisher
    The design, fabrication, and experimental demonstration of dynamically reconfigurable binary optical switches based on the integration of GaAs/AlGaAs vertical-cavity surface-emitting lasers and heterojunction phototransistors are reported. These new monolithic optical switches can perform spatial routing and optical amplification functions on input optical data with a fan-out of two, and can be programmed using simple voltage control. The 1 × 2 and 2 × 2 devices provide the basis for a high performance, two-dimensional optical switching fabric with electrical interfaces for optical switching and interconnection networks.
