Abstract

We have designed and simulated with the finite difference time domain method, an all-dielectric slot defect within a three-dimensional photonic band-gap crystal that produces a sharp defect state within the band gap showing a quality of factor exceeding 600 and field enhancement exceeding 25. At the slot defect the field at the resonance is localized in a volume smaller than 0.15(lambda)(3), far smaller than that achieved with previous defect modes in three-dimensional crystals.
