摘要
我们建议并且数字地表明 ultrafast 即时平常的微分方程(颂诗) 计算基于一个硅 microring 共鸣器在光地里联合起来，在象一个光时间的微分器的批评联合区域操作。作为一个信号处理系统的基本积木，一个消减器和 splitter 在建议结构被包括。这个计划在 silicon-on-insulator (SOI ) 上以高速度，紧缩的尺寸和集成被展示晶片。这个计算单位的尺寸仅仅是 35 m ???? 綔 ? 钋 ?? 亘 ? 疞? 鞬蒠鞪? 趬嶰? 椿 ???? m 吗？？
We propose and numerically demonstrate an ultrafast real-time ordinary differential equation （ODE） computing unit in optical field based on a silicon microring resonator, operating in the critical coupling region as an optical temporal differentiator. As basic building blocks of a signal processing system, a subtractor and a splitter are included in the proposed structure. This scheme is featured with high speed, compact size and integration on a siliconon-insulator （SOl） wafer. The size of this computing unit is only 35 μm × 45 μm. In this paper, the performance of the proposed structure is theoretically studied and analyzed by numerical simulations.
