    Abstract

    In this work, we present an innovative approach for designing small-scale microcavity resonators. By introducing a gold cladding around the structure, we may significantly reduce the mode volume and simultaneously increase the cavity's quality (Q)-factor. By making use of the TE011 mode, as opposed to the more traditional HE111 mode, we may further reduce the mode volume while taking advantage of decreased loss into the metal layer due to the optimal polarization choice. We demonstrate a means to design and optimize the cavity geometry to obtain desired spectral characteristics through the use of particle swarm optimization, and we present a cavity operating at 1.5 mu m with a Q value exceeding 300 000 and a modal volume of less than 0.9(lambda/n)(3).
