During the last decades, 2D-ordered and disordered photonic systems have attracted intense attention as systems capable to control and modify the flow of light. These structures can also localize light into a bandgap by exciting states arising from cavities, defects, or photonic molecules. We report a controllable random disordered photonic system of silicon dielectric cylinders that presents a deep bandgap and, superimposed, two tunable resonant states generated from decagonal ring resonators embedded into it. These states show a high transmission intensity and a bandwidth that remains stable when its geometrical parameters for frequency tuning are modified. The ability to tune resonating frequencies with geometrical parameters of the system allows interesting applications such as sensing and filtering. [ABSTRACT FROM AUTHOR] |
