ABSTRACT
Here we report on the optical properties associated with photonic bands of three-dimensional photonic colloidal crystals. Optical spectroscopy analysis shows fluctuations of the transmitted and reflected light intensity in photon frequency regions where no stop bands open up. The different optical features observed at low and high photon energy ranges are analyzed in terms of the band structure of the crystal. A relationship is found between dispersion of the bands and the features observed experimentally. On these premises, we show it is possible to map the higher-energy band region along nonprincipal directions of the first Brillouin zone by transmission spectroscopy. © 2004 American Institute of Physics.

    We demonstrate focusing of the microwave radiation by a planoconcave lens based on photonic crystal superlattice. The superlattice consists of dielectric rods of two different diameters. The structural modulation results in a narrow transmission subband inside the band gap. The subband is...

    Photonic crystal nanolasers have a drawback of weak vertical emission, which degrades the detection efficiency from above. We show that the vertical emission is enhanced greatly by introducing asymmetry to the cavity, so that Fourier components around the Brillouin zone boundary are shifted to...

    We theoretically investigated the performance of the photonic crystal superprism, that is, the propagating beam quality, the wavelength sensitivity, and the resolution as a narrow band filter at 1.5-µm-wavelength range. First, we defined the equi-incident-angle curve in the Brillouin zone....

    In photonic crystals composed of ferroelectrics, hybrid bands corresponding to new additional band gaps are expected to appear around the centre and boundaries of the Brillouin zone. We expect to discover the group-velocity anomaly modes related to the phonon-polariton branches in these hybrid...

    Modes of photonic crystal (PC) line-defect waveguides can have small group velocity away from the Brillouin zone edge. This property can be explained by the strong interaction of the modes with the bulk PC. An anticrossing of “index guided” and “gap guided” modes should...

    We demonstrate the controlled enhancement of photoresponsivity in a graphene photodetector by coupling to slow light modes in a long photonic crystal linear defect cavity. Near the Brillouin zone (BZ) boundary, spectral coupling of multiple cavity modes results in broad-band photocurrent...
