摘要： 可重构的光子组件和网络集成芯片被设想在实现高效集成光子信息处理中发挥关键作用。 电热调制光学效应（ETMOE）是硅光子器件的一种强大的热光调谐机制，通过局部焦耳加热实现精确的光学控制。 我们提出了一种严格且三维电子-光子共集成方法，结合温度与波长相关的材料特性的非线性数值耦合，全面模拟硅波导和谐振器中的ETMOE。 使用先进的真正三维数值仿真优化了基于铂的对称加热器，在实现高效ETMOE调谐的同时减轻了不对称的热量分布。 除了对完全集成的三维开关进行完整的设计和分析外，我们还评估了单模波导截止、加热器与波导间距、加热器尺寸和热耗散，为基于ETMOE的优化提供了框架。 这些发现有助于实现节能、可编程的光子系统，用于神经形态计算、光互连和可重构光子网络。 显示英文摘要

摘要： Reconfigurable integrated chips of photonic components and networks are envisaged to play a key role in realizing highly efficient integrated photonic information processing. Electrothermally modulated optical effect (ETMOE) is a powerful thermo-optic tuning mechanism for silicon photonic devices, enabling precise optical control via localized Joule heating. We present a rigorous and three-dimensional electronic-photonic co-integrated approach with the nonlinear numerical coupling of temperature and wavelength-dependent material properties to comprehensively model ETMOE in silicon waveguides and resonators. A platinum-based symmetric heater is optimized using advanced true 3D numerical simulations, achieving efficient ETMOE-based tuning while mitigating asymmetric heat distribution. In addition to a complete design and analysis of the fully integrated three-dimensional switch, we also evaluate single-mode waveguide cutoff, heater-to-waveguide separation, heater dimensions, and thermal dissipation, providing a framework for ETMOE-based optimization. The findings contribute to energy-efficient, programmable photonic systems for neuromorphic computing, optical interconnects, and reconfigurable photonic networks.
