In this paper, we present a novel, scalable, and reconfigurable optical switch that performs multiple computational logic functions simultaneously. The free-carrier depletion effect is used to perform non-volatile switching operations due to its high speed and low power consumption. We adopt the concept of optical memory using a phase-change material to realize the non-volatile reconfigurability without a constant power supply, in addition to providing a large operating bandwidth required for reconfigurability. The proposed reconfigurable optical logic architecture is realized in a compact microdisk resonator configuration, utilizing both the carrier-depletion-based modulation and phase-change optical memory. This is the first time these two modulation schemes are implemented in the same optical microdisk for the purpose of reconfigurable optical logic.
在本文中，我们展示了一种新颖、可扩展且可重构的光开关，它能同时执行多种计算逻辑功能。自由载流子耗尽效应因其高速和低功耗被用于执行非易失性开关操作。我们采用利用相变材料的光存储器概念来实现无需持续电源的非易失性可重构性，此外还提供可重构性所需的大工作带宽。所提出的可重构光逻辑架构是在紧凑的微盘谐振器配置中实现的，利用了基于载流子耗尽的调制和相变光存储器。这是首次将这两种调制方案在同一光学微盘中实现以用于可重构光逻辑。
