(a) SEM topview around the cavity. (b) Magnified view at the nanocavity. (c) Schematic band structure for the FP cavity. The dotted (solid) curve represents the nanocavity (FP) mode.
(a) Frequencies and for 15 resonant modes. (b) Band diagram of the line-defect waveguide in PC1. Parameters used in calculation are inserted.
(a) Illustration of FP cavity with nine missing air holes. [(b)–(d)] The profile of for the first to third FP modes along the dotted line in (a). Shaded parts indicate the cavity edges.
Near field images and polarization properties for four resonant modes. Corresponding frequencies and line defects structure are superimposed.
