描述了一种具有光I/O的现场可编程逻辑器件（FPLD）。具有光学I/O的FPLD可以通过下载控制比特流而具有在现场指定的功能，并且可以用于广泛的应用，例如光学信号处理、光学图像处理和光学互连。我们的设备实现了6个国家的最先进的动态可编程逻辑阵列（PLA的）上2毫米× 2毫米的模具。这些器件是通过朗讯技术高级研究项目协作组（Lucent/ARPA/COOP）利用0.5微米互补金属氧化物半导体自电光器件技术制造的，并于1998年交付。所有设备功能齐全：电子数据路径已在200 MHz上得到验证，光学测试正在进行中。该器件已被编程为实现具有六个4 × 4交叉开关的两级光交换网络，可以实现超过190 × 10（6）个唯一的可编程输入输出排列。同样的器件在2 cm x 2 cm的基板上可以支持多达4000个光学I/O和1 Tbit/s的光学I/O带宽，并通过大约110，000个可编程逻辑门提供完全可编程的数字功能。建议的光电FPLD也非常适合实现密集的，静态可重构的交叉开关。我们描述了一个有吸引力的应用领域，这样的设备：一个rechereseable三阶段的光开关的广域网骨干，交换1000流量流在OC-48的数据速率和支持几个太比特的流量。
A field-programmable logic device (FPLD) with optical I/O is described. FPLD's with optical I/O can have their functionality specified in the field by means of downloading a control-bit stream and can be used in a wide range of applications, such as optical signal processing, optical image processing, and optical interconnects. Our device implements six state-of-the-art dynamically programmable logic arrays (PLA's) on a 2 mm x 2 mm die. The devices were fabricated through the Lucent Technologies-Advanced Research Projects Agency-Consortium for Optical and Optoelectronic Technologies in Computing (Lucent/ARPA/COOP) workshop by use of 0.5-microm complementary metal-oxide semiconductor-self-electro-optic device technology and were delivered in 1998. All devices are fully functional: The electronic data paths have been verified at 200 MHz, and optical tests are pending. The device has been programmed to implement a two-stage optical switching network with six 4 x 4 crossbar switches, which can realize more than 190 x 10(6) unique programmable input-output permutations. The same device scaled to a 2 cm x 2 cm substrate could support as many as 4000 optical I/O and 1 Tbit/s of optical I/O bandwidth and offer fully programmable digital functionality with approximately 110,000 programmable logic gates. The proposed optoelectronic FPLD is also ideally suited to realizing dense, statically reconfigurable crossbar switches. We describe an attractive application area for such devices: a rearrangeable three-stage optical switch for a wide-area-network backbone, switching 1000 traffic streams at the OC-48 data rate and supporting several terabits of traffic.
