Modal reflectivity in finite-depth two-dimensional photonic-crystal microcavities [PDF]
, 1998 We present finite-difference time-domain calculations of the Q factor for an optical microcavity defined by a slab waveguide and two-dimensional photonic-crystal end mirrors.

Photonic Crystal Laser Accelerator Structures [PDF]
Conf.Proc.C030512:1855,2003, 2003 Photonic crystals have great potential for use as laser-driven accelerator structures. A photonic crystal is a dielectric structure arranged in a periodic geometry. Like a crystalline solid with its electronic band structure, the modes of a photonic crystal lie in a set of allowed photonic bands.

Complete photonic bandgaps in supercell photonic crystals [PDF]
Phys. Rev. A 96, 051802 (2017), 2017 We develop a class of supercell photonic crystals supporting complete photonic bandgaps based on breaking spatial symmetries of the underlying primitive photonic crystal. One member of this class based on a two-dimensional honeycomb structure supports a complete bandgap for an index-contrast ratio as low as $n_{high}/n_{low} = 2.1$, making this the ...

Simple model of the density of states in 1D photonic crystal [PDF]
Proc. SPIE 5950, 59501A (2005), 2010 In this paper, we present a simple, yet versatile, analytical model of one-dimensional photonic crystal (1D PC). In our theoretical model, we take into account direction of propagation and therefore do not neglect anisotropic nature of photonic crystals.

Phys. Rev. X 4, 041014 (2014), 2014 We introduce a new "universality class" of artificial optical media - photonic hyper-crystals. These hyperbolic metamaterials with periodic spatial variation of dielectric permittivity on subwavelength scale, combine the features of optical metamaterials and photonic crystals.

Performance optimization of planar photonic crystal bound states in the continuum cavities: mitigating finite-size effects [PDF]
Frontiers of OptoelectronicsBound states in the continuum (BICs) offer a promising solution to achieving high-quality factor (Q factor) cavities. However, finite-size effects severely deteriorate the BIC mode in practical applications.

Self-trapping of light and nonlinear localized modes in 2D photonic crystals and waveguides [PDF]
arXiv, 2001 We overview our recent results on the nonlinear localized modes in two-dimensional (2D) photonic crystals and photonic-crystal waveguides. Employing the technique based on the Green function, we describe the existence domains for nonlinear guided modes in photonic crystal waveguides and study their unique properties including bistability.
