17. Observation of PT-symmetry breaking in complex optical potentials.

Author

Guo A, Salamo GJ, Duchesne D, Morandotti R, Volatier-Ravat M, Aimez V, Siviloglou GA, and Christodoulides DN

Abstract

In 1998, Bender and Boettcher found that a wide class of Hamiltonians, even though non-Hermitian, can still exhibit entirely real spectra provided that they obey parity-time requirements or PT symmetry. Here we demonstrate experimentally passive PT-symmetry breaking within the realm of optics. This phase transition leads to a loss induced optical transparency in specially designed pseudo-Hermitian guiding potentials.

18. Beam dynamics in PT symmetric optical lattices.

Author

Makris KG, El-Ganainy R, Christodoulides DN, and Musslimani ZH

Abstract

The possibility of parity-time (PT) symmetric periodic potentials is investigated within the context of optics. Beam dynamics in this new type of optical structures is examined in detail for both one- and two-dimensional lattice geometries. It is shown that PT periodic structures can exhibit unique characteristics stemming from the nonorthogonality of the associated Floquet-Bloch modes. Some of these features include double refraction, power oscillations, and eigenfunction unfolding as well as nonreciprocal diffraction patterns.

19. Blocking and routing discrete solitons in two-dimensional networks of nonlinear waveguide arrays.

Author

Christodoulides DN and Eugenieva ED

Abstract

It is shown that discrete solitons can be navigated in two-dimensional networks of nonlinear waveguide arrays. This can be accomplished via vector interactions between two classes of discrete solitons: signals and blockers. Discrete solitons in such two-dimensional networks can exhibit a rich variety of functional operations, e.g., blocking, routing, logic functions, and time gating.
