Abstract
We propose a novel type of nanowire (NW)-induced nanocavity based on photonic crystal disks, and we investigate its design by three-dimensional finite-difference time-domain calculations. We detail the confinement principle used in such a cavity and discuss the influence of geometric and material parameters on the cavity performance. Finally, we report on an optimized design presenting a quality factor , a mode volume as small as , and a large confinement factor of the electric field energy in the NW , which shows good prospects for the realization of efficient NW-based nanolasers operating in the ultraviolet and visible ranges.
