Transverse Anderson localization of light near Dirac points of photonic nanostructures
Hanying Deng, Xianfeng Chen, Boris A. Malomed +2
We perform a comparative study of the Anderson localization of light beams in disordered layered photonic nanostructures that, in the limit of periodic layer distribution, possess…
Accurate near-field calculation in the rigorous coupled-wave analysis method
Martin Weismann, Dominic F. G. Gallagher, Nicolae C. Panoiu
The rigorous coupled-wave analysis (RCWA) is one of the most successful and widely used methods for modeling periodic optical structures. It yields fast convergence of the electrom…
Generation of Subwavelength Plasmonic Nanovortices via Helically Corrugated Metallic Nanowires
Changming Huang, Xianfeng Chen, Abiola O. Oladipo +2
We demonstrate that plasmonic helical gratings consisting of metallic nanowires imprinted with helical grooves or ridges can be used efficiently to generate plasmonic vortices with…
Theory of Pulsed Four-Wave-Mixing in One-dimensional Silicon Photonic Crystal Slab Waveguides
Spyros Lavdas, Nicolae C. Panoiu
We present a comprehensive theoretical analysis and computational study of four-wave mixing (FWM) of optical pulses co-propagating in one-dimensional silicon photonic crystal waveg…
Optically and Electrically Tunable Dirac Points and Zitterbewegung in Graphene-Based Photonic Superlattices
Hanying Deng, Fangwei Ye, Boris A. Malomed +2
We demonstrate that graphene-based photonic superlattices provide a versatile platform for electrical and all-optical control of photonic beams with deep-subwavelength accuracy. Sp…
Nonlinear generalized source method for modeling second-harmonic generation in diffraction gratings
Martin Weismann, Dominic F. G. Gallagher, Nicolae C. Panoiu
We introduce a versatile numerical method for modeling light diffraction in periodically patterned photonic structures containing quadratically nonlinear non-centrosymmetric optica…
