Field Confinement and Quality Factor of the Multilayer Cavity Resonators

Yogesh, N., Subramanian, V.·2011·Journal of Applied Physics

Abstract

The field confinement aspect of a multilayer cavity resonator formed by a one-dimensional photonic crystal with prism wedge configuration is described in this paper. The prism wedge consists of alternating dielectric layers and is used for the construction of polygon multilayered structures with different symmetries like C4v-square and C6v-hexagon. Field confinement is studied by finding the resonant modes and quality factors (Q) of the proposed geometries. The computed Q factors for the two-dimensional geometries (the third dimension is taken to be infinity) are of the order of 103–107. On the other hand, for the finite height of the cavity, the estimated Q factor is found to be of the order of 104. An attempt has been taken to achieve the vertical confinement of light for a few of the resonant modes so that the proposed cavities may be implemented for microwave applications, especially in spectroscopic techniques.

  • In a realistic scenario, absorption, scattering and coupling losses degrade the quality factor of the microcavity.

    “In a realistic scenario, where absorption, scattering and coupling losses degrade the quality factor of the microcavity [286,287], both the materials and the preparation techniques used for Bragg stacks become decisive and strongly influence the value of Q.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
