Data from: Modelling and simulation of thermally-induced optical transparency in a dual-microring 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 130nm 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 4.29nm. For a simulated heater current of 7mA (55.7mW heater power) applied to one of the through coupling heaters, the optical transparency exhibits a red shift of 1.79nm from the reference resonant wavelength. The ring to ring separation of approximately 900nm 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.
