Slanted-pore photonic band-gap materials.
We present a detailed analysis of three-dimensional photonic band-gap materials consisting of lattices of slanted pores with n = 2 , 3, and 4 pores per unit cell. These slanted pores emanate from one or two masks consisting of a two-dimensional square or triangular lattice of holes placed on the top surface of the crystal. We also consider the case in which the top surface is "polished" at an a...
متن کاملMetallic photonic-band-gap filament architectures for optimized incandescent lighting
We identify an optimized three-dimensional metallic photonic-band-gap filament architecture for electrically pumped, quasithermal, visible light emission. This identification is based on extensive band structure and finite-difference time-domain calculations of metallic photonic crystals. The optimum structure consists of an inverse square-spiral photonic crystal, exhibiting a large bandwidth o...
متن کاملNonlinear Bloch waves in metallic photonic band-gap filaments
We demonstrate the occurrence of nonlinear Bloch waves in metallic photonic crystals PCs . These periodically structured filaments are characterized by an isolated optical pass band below an effective plasma gap. The pass band occurs in a frequency range where the metallic filament exhibits a negative, frequencydependent dielectric function and absorption loss. The metallic losses are counterba...
متن کاملLattice Boltzmann model for photonic band gap materials.
An efficient technique for computing photonic band structure and defect modes is proposed based on the lattice Boltzmann model. Physically, it is a scheme based on the kinetics of the virtual microscopic process, rather than a solution of the macroscopic Maxwell equations. The method has significant advantages of being naturally suited for massively parallel machine, as well as speed and conven...
متن کاملResonance Raman scattering in photonic band-gap materials
We study the resonance Raman scattering of light from a three-level atom embedded in a photonic band-gap material or in a frequency dispersive medium whose photon spectrum exhibits a gap due to photon coupling to medium excitations such as excitons and optical phonons. We demonstrate that the one-particle spectrum of the system consists of either a continuous part with energy lying outside the ...
