Oral/2009: Manipulation of Interface Solitons in Quadratic Nonlinear Photonic Lattices
Zhiyong Xu1, Yuri Kivshar1
1Nonlinear Physics Centre, RSPE, Australian National University
Abstract: We study the properties of nonlinear waves localized at an interface between two different optical lattices in nonlinear quadratic media, in particular focusing on the...
Oral/2009: Control of cavity modes in coupled periodic waveguides
Andrey Sukhorukov1, Andrei Lavrinenko1,2, Sangwoo Ha1, Yuri Kivshar1
1Nonlinear Physics Centre, Research School of Physics and Engineering, Australian National University, Australia
2DTU Fotonik, Department of Photonics Engineering, Technical University of Denmark, Denmark

Abstract: We demonstrate that the modes of coupled cavities created in periodic waveguides can depend critically on the lateral shift between the cavities. In the absence...
Poster/2010: Longitudinal Shift in Coupled Nanobeams and Mode Degeneracy
