(OPTICAL SOC AMER, 2010-09-01)We analyze localization of light in honeycomb photonic lattices restricted in one dimension, which can be regarded as an optical analog of graphene nanoribbons. We discuss the effect of lattice topology on the properties ...
-
(OPTICAL SOC AMER, 2006-06-01)We discuss the formation of self-trapped localized states near the edge of a semi-infinite array of nonlinear optical waveguides. We study a crossover from nonlinear surface states to discrete solitons by analyzing the ...
-
(OPTICAL SOC AMER, 2006-08-01)We analyze discrete surface modes in semi-infinite binary waveguide arrays, which can support simultaneously two types of discrete solitons. We demonstrate that the analysis of linear surface states in such arrays provides ...
-
(2007)We study nonlinear surface modes in two-dimensional anisotropic periodic photonic lattices and demonstrate that, in a sharp contrast to one-dimensional discrete surface solitons, the mode threshold power is lower at the ...
-
(ELSEVIER, 2006-01-30)We study the properties of localized impurity modes and the transmission of plane waves across a general nonlinear impurity embedded in an infinite one-dimensional linear chain. Using the formalism of the lattice Green ...
-
(2007)We discuss the formation of guided modes localized at the interface separating two different periodic photonic lattices. Employing the effective discrete model, we analyze linear and nonlinear interface modes and also ...
-
(OPTICAL SOC AMER, 2008-12-01)We analyze localization of light at the interfaces separating square and hexagonal photonic lattices, as recently realized experimentally for two-dimensional laser-written waveguides in silica glass with self-focusing ...
-
(2007)We study the properties of junctions created by the crossing of N identical branches of linear discrete networks. We reveal that for N > 2 such a junction creates a topological defect and supports two types of spatially ...
-
(2009-09-14)We study the dynamics of a pair of nonlinear split-ring resonators (a ‘metadimer’) excited by an alternating magnetic field and coupled magnetically. Linear metadimers of this kind have been recently used as the elementary ...
-
(OPTICAL SOC AMER, 2008-05-01)We study light localization at a phase-slip defect created by two semi-infinite mismatched identical arrays of coupled optical waveguides. We demonstrate that the nonlinear defect modes possess the specific properties of ...
-
(OPTICAL SOC AMER, 2010-08-15)We study experimentally light localization at phase-slip waveguides and at the intersection of phase-slips in a two-dimensional (2D) square photonic lattice. Such system allows to observe a variety of effects, including ...
-
(AMERICAN PHYSICAL SOC, 2006-08-25)We report on the observation of surface gap solitons found to exist at the interface between uniform and periodic dielectric media with defocusing nonlinearity. We demonstrate strong self-trapping at the edge of a LiNbO3 ...
-
(AMER PHYSICAL SOC, 2008-05)We numerically study both linear and nonlinear surface modes in semi-infinite chirped two-dimensional photonic lattices in the framework of an effective discrete nonlinear model. We demonstrate that the lattice chirp can ...
-
(AMER PHYSICAL SOC, 2012-02-13)We introduce a novel concept of surface bound states in the continuum, i.e., surface modes embedded into the linear spectral band of a discrete lattice. We suggest an efficient method for creating such surface modes and ...
