Abstract
We propose a high-Q photonic crystal cavity formed by introducing random disorder to the central region of an otherwise defect-free photonic crystal slab (PhC). Three-dimensional finite-difference time-domain simulations determine the frequency, quality factor, Q, and modal volume, V, of the localized modes formed by the disorder. Relatively large Purcell factors of 500-800 are calculated for these cavities, which can be achieved for a large range of degrees of disorders. © 2014 by the authors; licensee MDPI, Basel, Switzerland.
