Observation of dipolar transport in one-dimensional photonic lattices
We experimentally study the transport properties of dipolar and fundamental modes on one dimensional (1D) coupled waveguide arrays. By carefully modulating a wide optical beam, we are able to effectively excite dipolar or ...
Interface solitons in quadratic nonlinear photonic lattices
We study the properties of two-color nonlinear localized modes which may exist at the interfaces separating two different periodic photonic lattices in quadratic media, focusing on the impact of phase mismatch of the ...
Quantum localized states in photonic flat-band lattices
(American Physical Society, 2017)
The localization of light in flat-band lattices has been recently proposed and experimentally demonstrated in several configurations, assuming a classical description of light. Here we study the problem of light localization ...
Compact four-port circulator based on 2D photonic crystals with a 90° rotation of the light wave for photonic integrated circuits applications
(Institute of Physics Publishing, 2019)
A four-port optical circulator based on two-dimensional square lattice photonic crystals is reported. It is simple besides the brief framework. The crystalline geometrical structure of the circulator makes 90° non-reciprocal ...
Diffraction-free image transmission in kagome photonic lattices
We study the propagation of non-diffracting images in kagome photonic lattices. In a weak-coupling regime (discrete approach), the linear spectrum is composed by only three bands, including a completely degenerated and ...
Surface solitons in chirped photonic lattices
We study surface modes at the edge of a semi-infinite chirped photonic lattice in the framework of an effective discrete nonlinear model. We demonstrate that the lattice chirp can change dramatically the conditions for the ...
Nonlinear localized modes at phase slips in two-dimensional photonic lattices
We analyze the existence and stability of nonlinear modes localized at phase-slip waveguide channels and their intersections in two-dimensional photonic lattices with rectangular symmetry. While in linear lattices only one ...
Flat band light dynamics in stub photonic lattices
(Nature Publishing Group, 2017)
We experimentally study a Stub photonic lattice and excite their localized linear states originated from an isolated Flat Band at the center of the linear spectrum. By exciting these modes in different regions of the ...
Observation of localized ground and excited orbitals in graphene photonic ribbons
(IOP Publishing Ltd, 2018)
We report on the experimental realization of a quasi-one-dimensional photonic graphene ribbon supporting four flat-bands (FBs). We study the dynamics of fundamental and dipolar modes, which are analogous to the s and p ...
