New trends in nonlinear photonics: From binary waveguide arrays to novel PT-symmetric optical systems and graphene based devices

Alejandro Aceves
Southern Methodist University

The last few years, we have experienced substantial advancements in Optics and Photonics which have been identified as essential technologies with incredible economic and social impact. Recent findings at the fundamental level on the optical properties of graphene and the notion of Parity Time symmetry as it extends to optics and photonics, as well as progress made in engineering meta-materials have led to research aimed to build smaller, faster on more efficient devices over an ever larger range of frequencies. It is also the case that some photonic-based models can be ideal Laboratories to study fundamental physical processes such as Rogue waves, Anderson localization and neutrino oscillations. In this talk we will highlight a few examples and how their modeling can be captured and explained by universal coupled mode equations resembling the Dirac equations and the Massive Thirring Model.
