Comparative Analysis of a Planar Slotted Microdisk Resonator
We analyze a microdisk resonator of sub-micrometer radius where confinement is obtained in a vertical sandwich characterized by a central slot of lower refractive index material. The properties of the antiguiding even modes characterized by TM fields peaked in the slot are analyzed with specific ref...

Summary: | We analyze a microdisk resonator of sub-micrometer radius where confinement is obtained in a vertical sandwich characterized by a central slot of lower refractive index material. The properties of the antiguiding even modes characterized by TM fields peaked in the slot are analyzed with specific reference to the resonant wavelengths, the quality factor, the mode confinement properties, and the Purcell factor. It is shown, by means of a comparative analysis, that, for a small disk radius a full vectorial approach is required in order to properly account for the hybrid nature of the modes. This reflects on the dependence of such figures of merit upon geometrical parameters of the structure. |
