We describe the recent advances in a monolithic optoelectronic technology based on the integration of two-dimensional arrays of cascadable optical switches and optical logic gates consisting of vertical-cavity surface-emitting lasers (VCSEL's) and heterojunction phototransistors or photothyristors. Different combinations of these components can perform optical switching, logic, memory, and regeneration. Latching, nonlatching, and bistable switches with high optical gain and contrast are demonstrated by using a single GaAs-AlGaAs epilayer design along with single-stage Boolean optical logic functions: AND, OR, IDENTITY, INVERT, NAND, NOR, and XOR. As an application to parallel, digital arithmetic logic, we describe a simple, compact, two-chip binary adder, which uses optical symbolic substitution and two-dimensional VCSEL-PNPN logic gate arrays.
我们描述了一种基于可级联光开关二维阵列与由垂直腔面发射激光器（VCSEL）以及异质结光电晶体管或光晶闸管组成的光逻辑门集成的单片光电子技术的最新进展。这些组件的不同组合可实现光开关、逻辑、存储和再生功能。通过使用单一的GaAs - AlGaAs外延层设计以及单级布尔光逻辑函数（与、或、恒等、非、与非、或非和异或），展示了具有高光增益和对比度的锁存、非锁存和双稳态开关。作为并行数字算术逻辑的应用，我们描述了一种简单、紧凑的双芯片二进制加法器，它使用光符号替换和二维VCSEL - PNPN逻辑门阵列。
