Free-space optical system based on vertical-cavity surface-emitting lasers and self-electro-optic effect devices

摘要

A cascaded optical logic system is reported in which an array of vertical-cavity surface-emitting lasers (VCSELs) selectively controls an array of symmetric self-electro- optic effect devices (S-SEEDs). This configuration allows interconnect masks to be reconfigured dynamically by selectively disabling microlasers through a host controller. A single-array system in which an optical input is sequenced through successive rows of an S-SEED array is demonstrated. The system is operated by setting the initial states of the S-SEEDs using the VCSELs and then optically scrolling the data from row to row.
