title: Optical range microcavities and filters using multiple dielectric layers in metal-insulator-metal structures.
abstract: We present a technique to adjust omnidirectional resonances in planar metallic microcavity structures. It is demonstrated numerically with realistic material parameters that by changing the thickness of different dielectric layers in metal-dielectric-metal structures, the omnidirectional resonance can be chosen to lie at an arbitrary frequency in the optical range. These ideas can also be applied to design a high-pass filter in the optical frequency range.
