光学可编程门阵列（OPGA）是传统FPGA的光学版本，它得益于光存储器和逻辑电路之间的直接并行接口。OPGA利用由vcsel阵列访问的全息存储器来编程其逻辑。集成到OPGA芯片中的有源像素传感器阵列使得可以在很短的时间内对逻辑进行光学寻址，从而允许快速动态重新配置。将空间复用和移位复用相结合，将配置页存储在存储器中，使OPGA模块更加紧凑。OPGA的重构能力可以更有效地解决模式识别和数据库搜索等问题。
The Optically Programmable Gate Array (OPGA), an optical version of a conventional FPGA, benefits from a direct parallel interface between an optical memory and a logic circuit. The OPGA utilizes a holographic memory accessed by an array of VCSELs to program its logic. An active pixel sensor array incorporated into the OPGA chip makes it possible to optically address the logic in a very short time allowing for rapid dynamic reconfiguration. Combining spatial and shift multiplexing to store the configuration pages in the memory, the OPGA module can be made compact. The reconfiguration capability of the OPGA can be applied to solve more efficiently problems in pattern recognition and database search.
