The transmission properties of close-packed opal-based photonic crystals with a SiO 2 (n=1.5) matrix have been examined using the transfer matrix method. The response for bare, sintered and coated opals at the X- and L-points has been studied, which corresponds to plane waves normally incident onto the (100) and (111) crystal planes. The incomplete gap at the L-point fully inhibits the transmission...
Using the transfer matrix technique the transmission response of a rectangular lattice photonic crystal with and without a planar cavity defect has been studied. The response has been studied both within and out of the periodic plane of the crystal for both the perfect and planar cavity defect crystal. The planar cavity defect in the crystal introduces a defect state into the photonic band gap region...
Summary form only given. Using the transfer matrix method the transmission co-efficient was determined for periodic defect states in a hexagonal lattice. The hexagonal lattice is created by removing cylindrical air holes from a background dielectric media with a dielectric constant of 7.9. This value was chosen to represent a half-wavelength thick GaAs waveguide from which the cylindrical holes were...
