可重构光子集成器件和电路对于许多应用来说非常重要。在实现可重构性的各种机制中，热光效应很受欢迎，因为它具有多种材料的可用性、设计简单且易于制造。特别是，硅具有较大的热光系数和较高的导热率，因此有望实现高效的热可重构硅光子集成器件和电路。本文回顾了最近的进展。首先，总结了基于不同结构的热可调硅光子滤波器，包括微环谐振器（MRR）和MRR辅助马赫-曾德尔干涉仪（MZI）。其次，回顾了基于 MZI 和 MRR 的硅光子开关。最后，对为量子光子学、微波光子学和光互连应用而开发的热可重构硅光子集成电路进行了综述。
Reconfigurable photonic integrated devices and circuits are very important for many applications. Among various mechanisms for realizing reconfigurability, thermo-optic effect is popular because of the availability for many materials, the design simplicity and the fabrication ease. In particular, silicon has a large thermo-optic coefficient as well as a high heat conductivity, and thus it is promising to realize efficient thermally-reconfigurable silicon photonic integrated devices and circuits. Recent progress is reviewed in this paper. First, thermally-tunable silicon photonic filters based on different structures are summarized, including microring resonators (MRRs) and MRRs-assisted Mach-Zehnder interferometers (MZIs). Second, silicon photonic switches based on MZIs and MRRs are reviewed. Finally, a review is given for thermally-reconfigurable silicon photonic integrated circuits developed for the applications in quantum photonics, microwave photonics, and optical interconnects.
