Abstract

The optimized design of a photonic platform based on a nanowire light emitting diode (LED) and a nanowire photodetector connected with a waveguide is proposed. The light coupling efficiency from the LED to the detector is optimized as a function of the geometrical parameters of the system using the finite difference time domain simulation tool Lumerical. Starting from a design reported in the literature with a coupling efficiency of only 8.7%, we propose an optimized photonic platform with efficiency reaching 65.5%.

摘要

提出了一种基于纳米线发光二极管（LED）和与波导相连的纳米线光电探测器的光子平台的优化设计。使用时域有限差分模拟工具Lumerical，根据系统的几何参数优化从LED到探测器的光耦合效率。从文献报道的耦合效率仅为8.7%的设计出发，我们提出了一种优化的光子平台，其效率达到65.5%。
