This microcavity is formed by a single-row photonic crystal (PhC) embedded in a 500-nm-wide photonic wire waveguide - and is based on silicon-on-insulator. A normalized transmission of 85%, together with a Q-factor of 18 500, have been achieved experimentally through the use of carefully designed tapering on both sides of each of the hole-type PhC mirrors that form the microcavity. We have also demonstrated reasonably accurate control of the cavity resonance frequency. Simulation of the device using a three-dimensional finite-difference time-domain approach shows good agreement with the experimental results. publisher: IEEE date: 2008-01-01 type: Articles type: PeerReviewed format: text language: en identifier: https://eprints.gla.ac.uk/5931/1/5931.pdf identifier: Zain, A.R.M., Gnan, M., Chong, H.M.H., Sorel, M. and De La Rue, R.M.
