Paper Abstract

A photonic-plasmonic integration scheme was devised to displace the defect-mode field of a photonic crystal (PC) slab cavity from the spatial center to the surface of the slab. The device was constructed by placing an isolated metallic structure on the top surface of a missing-hole defect in the PC. Excitation of the metal's surface plasmon resonance mode by the PC cavity's defect mode was investigated using a three-dimensional plane wave transfer matrix method. It was revealed that using the PC cavity could minimize the background field around the metal, significantly enhancing the field intensity contrast between the metal and surrounding dielectric.
