Three-Dimensional Beam Propagation Modeling of Nanostructured Whispering-Gallery Microcavities
Using a scalar 3-D beam propagation technique in a cylindrical coordinate system, we demonstrate that a nanohole bored in a whispering-gallery microcavity sensor with an inserted 25-nm-radius polystyrene particle can dually enhance the detection signal (by a factor of ~6) and maintain a quality fact...

| description | Using a scalar 3-D beam propagation technique in a cylindrical coordinate system, we demonstrate that a nanohole bored in a whispering-gallery microcavity sensor with an inserted 25-nm-radius polystyrene particle can dually enhance the detection signal (by a factor of ~6) and maintain a quality factor of 7.6 × 10<sup>8</sup> (after degradation by a factor as little as 3) at a wavelength of 633 nm. Detailed numerical characterization of the resonant light circulating in this nanostructured cavity is provided, including aspects of stability and convergence. |
