硅材料折射率的高温敏感性限制了硅基微环谐振器在集成光子学中的应用。为了实现低而宽的温变波长位移微波谐振器，设计宽带无热波导成为一项重要的任务。在这项工作中，我们提出了一个宽带无热波导，显示出低的有效热光系数为±1×10−6/K从1400到1700 nm。该波导应用于环形谐振器时，具有低损耗和稳定的宽带无热特性，半径大于30 μm的环形谐振器的弯曲损耗为0.02 dB/cm。
The high-temperature sensitivity of the silicon material index limits the applications of silicon-based micro-ring resonators in integrated photonics. To realize a low but broadband temperature-dependent-wavelength-shift microring resonator, designing a broadband athermal waveguide becomes a significant task. In this work, we propose a broadband athermal waveguide that shows a low effective thermo-optical coefficient of ±1×10−6/K from 1400 to 1700 nm. The proposed waveguide shows a low-loss performance and stable broadband athermal property when it is applied to ring resonators, and the bending loss of ring resonators with a radius of >30 μm is 0.02 dB/cm.
