چکیده
Nonlinear Physics Center, Research School of Physical Sciences and Engineering, Australian National University, Canberra ACT 0200, Australia 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 predict the existence of stable interface solitons including the hybrid staggered/unstaggered lattice solitons with the tails belonging to spectral gaps of different types. c © 2008 Optical Society of America

Nonlinear surface modes and Tamm states in periodic photonic structures
We study the formation of nonlinear localized modes and discrete surface solitons near the edges or interfaces of weakly coupled nonlinear optical waveguides, one-dimensional photonic crystals. We draw an analogy between the staggered nonlinear surface optical modes and the surface Tamm states known in the electronic theory. We discuss the crossover between discrete solitons inside the array an...
متن کاملSpatial Optical Solitons in Waveguide Arrays
We overview theoretical and experimental results on spatial optical solitons excited in arrays of nonlinear waveguides. First, we briefly summarize the basic properties of the discrete nonlinear Schrödinger (NLS) equation frequently employed to study spatially localized modes in arrays, the so-called discrete solitons. Then, we introduce an improved analytical model that describes a periodic st...
متن کاملSelf-deflecting plasmonic lattice solitons and surface modes in chirped plasmonic arrays.
We show that chirped metal-dielectric waveguide arrays with focusing cubic nonlinearity can support plasmonic lattice solitons that undergo self-deflection in the transverse plane. Such lattice solitons are deeply subwavelength self-sustained excitations, although they cover several periods of the array. Upon propagation, the excitations accelerate in the transverse plane and follow trajectorie...
متن کاملSurface solitons in two-dimensional quadratic photonic lattices
Two-dimensional surface solitons have been recently predicted to exist as novel types of discrete solitons localized in the corners or at the edges of two-dimensional photonic lattices. These theoretical predictions were followed by the experimental observation of twodimensional surface solitons in optically-induced photonic lattices and waveguide arrays laser-written in fused silica. Important...
متن کاملNonlinear localized modes at phase-slip defects in waveguide arrays.
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 both nonlinear surface modes and discrete solitons. We analyze the stability of the localized modes and their generation in both linear and nonlinear regimes.
