(a) The surface band structure for the (10) surface of a square PhC slab of dielectric rods in air, the radius of rods is ( is the lattice constant), the height of the rods is , and the dielectric constant of the rods is 11.56. The radius of the rods at the surface is . (b) The surface band structure for the surface of a triangular PhC slab of air holes extending through a high-index finite-height dielectric slab, the radius of holes is , and the high-index slab is of thickness . The distance between the centers of first right holes and the right boundary of the dielectric is .
(a) Top view of the microcavity composed by a 2D square PhC slab. (b) Top view of the microcavity composed by a 2D triangular PhC slab. The length of the cavities is denoted by .
(a) Field cross sections for the surface resonant mode in the square PhC slab cavity, showing the component of the electric field. (b) and (c) Field cross sections for the two surface resonant modes [ and ] in the triangular PhC slab cavity, showing the component of the magnetic field. Solid lines are outlines of the rods/holes/slabs.
The quality factor is plotted as a function of the length for the microcavity in (a) a square PhC slab and (b) a triangular PhC slab. Corresponding structures are illustrated in Fig. 2.
