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.
描述了一种具有光输入/输出的现场可编程逻辑器件（FPLD）。带有光输入/输出的FPLD可通过下载控制位流在现场指定其功能，并可用于广泛的应用，如光信号处理、光图像处理和光互连。我们的器件在一个2毫米×2毫米的芯片上实现了六个最先进的动态可编程逻辑阵列（PLA）。这些器件是通过朗讯科技-高级研究计划局-计算光学与光电子技术联盟（朗讯/ARPA/COOP）研讨会，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。所有器件均功能齐全：电子数据路径已在200兆赫兹下得到验证，光测试正在进行中。该器件已被编程以实现一个带有六个4×4交叉开关的两级光交换网络，该网络可实现超过190×10⁶种独特的可编程输入-输出排列。同样的器件若扩展到2厘米×2厘米的衬底上，可支持多达4000个光输入/输出和1太比特/秒的光输入/输出带宽，并提供具有约110000个可编程逻辑门的完全可编程数字功能。所提出的光电子FPLD也非常适合实现密集的、静态可重构的交叉开关。我们描述了这类器件的一个有吸引力的应用领域：一种用于广域网骨干网的可重排三级光开关，以OC-48数据速率交换1000个业务流并支持数太比特的业务量。
