光学导向逻辑器件是采用光开关网络执行逻辑运算的典型应用,光学网络中每一个开关的状态由施加到该开关的电学布尔信号决定。网络中每一个光开关的操作都是独立于其他光开关的操作,并且操作运算结果以光速在网络中传播。因此,光学导向逻辑器件具有非常高的运行速度,且总延迟非常小。硅基微环谐振器由于其尺寸小、功耗低、与CMOS工艺兼容等特性成为构建光学导向逻辑器件的理想单元器件。基于硅基微环谐振器的光学导向逻辑器件很容易实现大规模集成和低成本制备,已经提出并实现的基于硅基微环谐振器的光学导向逻辑器件包括“或/或非”、“与/与非”、“异或/同或”、编码器、译码器和半加器等。回顾了本课题组基于硅基微环谐振器实现的光学导向逻辑器件的研究成果和该领域的最新发展。 Optical guidance logic is a typical application that uses optical switching networks to perform logic operations. The state of each switch in an optical network is determined by the electrical Boolean signal applied to that switch. The operation of each optical switch in the network is independent of the operation of other optical switches, and the result of the operation operation propagates through the network at the speed of light. Therefore, the optical steering logic has a very high speed of operation, and the total delay is very small. Due to its small size, low power consumption and compatibility with CMOS technology, silicon-based micro-ring resonators become the ideal unit for building optical oriented logic devices. Optical guided logic devices based on silicon-based micro-ring resonators are easy to realize large-scale integration and low cost. Optical guided logic devices based on silicon-based micro-ring resonators have been proposed and implemented, including “” or “ ”And / and non “, ”XOR / same or ", encoder, decoder and half adder. The research results of optical guided logic devices based on Si-based micro-ring resonators and the latest developments in this field are reviewed.
