Data from: Modelling and simulation of a thermally induced optical transparency in a dual micro-ring resonator

This paper introduces the simulation and modelling of a novel dual micro-ring resonator. The geometric configuration of the resonators, and the implementation of a simulated broadband excitation source, results in the realization of optical transparencies in the combined through port output spectrum. The 130 nm silicon on insulator rib fabrication process is adopted for the simulation of the dual-ring configuration. Two titanium nitride heaters are positioned over the coupling regions of the resonators, which can be operated independently, to control the spectral position of the optical transparency. A third heater, centrally located above the dual resonator rings, can be used to red shift the entire spectrum to a required reference resonant wavelength. The free spectral range with no heater currents applied is 4.29 nm. For a simulated heater current of 7 mA (55.7 mW heater power) applied to one of the through coupling heaters, the optical transparency exhibits a red shift of 1.79 nm from the reference resonant wavelength. The ring-to-ring separation of approximately 900 nm means that it can be assumed that there is a zero ring-to-ring coupling field in this model. This novel arrangement has potential applications as a gas mass airflow sensor or a gas species identification sensor.本论文介绍了一种新型双微环谐振器（dual micro-ring resonator）的仿真与建模工作。该谐振器的几何构型结合模拟宽带激励源的搭建方案，可在组合直通端口输出光谱中实现光学透明特性（optical transparency）。针对该双环结构的仿真，本研究采用130 nm绝缘体上硅（silicon on insulator）脊形波导制造工艺。在谐振器的耦合区域上方部署了两个氮化钛加热器，二者可独立调控，以此精准控制光学透明特性的光谱位置。还设有第三个加热器位于双谐振环的中央上方，可用于将整个光谱红移至所需的参考谐振波长。未施加加热器电流时的自由光谱范围（free spectral range）为4.29 nm。当向其中一个耦合加热器施加7 mA的仿真加热器电流（对应加热器功耗55.7 mW）时，该光学透明特性相较于参考谐振波长产生1.79 nm的红移。双环间距约为900 nm，因此本模型中可假定环间耦合场为零。该新型结构具备作为气体质量流量传感器或气体种类识别传感器的应用潜力。
