Abstract
We demonstrate Photonic Coherence Phenomena such as the Coupled Resonator-Induced Transparency (CRIT) in novel configurations of double microring resonator hybrids. The most common configuration of ring resonator coupling involves evanescent or direct-coupling (DC). This involves physical separation and evanescent coupling between the bus input/output waveguide and the ring resonator. We make use of the novel coupling mechanism called cross-coupling which involves physical connection between the coupler’s in and out ports with profound effects on the response of the double resonator. Earlier studies have already demonstrated double ring resonators’ responses using cross-coupling for both bus waveguide-lower ring coupling and lower-upper ring coupling. “Hybrids” imply cases for when one coupling is direct- coupling and one cross-coupling, allowing for two new designs. This research is composed of three parts: i) Analytical simulation of novel double ring resonators ii) Computer Aided Design Photonic simulation and GDS conversion using Ansys Lumerical Software and KLayout (iii) Fabrication and characterization of deigns via DOST Research attachment in Nanophotonic Technology Center of the Polytechnic University of Valencia in Valencia City in Spain. This three-part approach ensures that the novel designs and desired coherence effects are observed and used for many potential integrated photonic applications such as in gyroscopes and telecommunications to name a few.
