Parity-Time Photonic Synthetic Media: From Nonlinear and Singular Optics to Lasing
Abstract
The objective of this project is to investigate new optical phenomena created from the interaction of PT (Parity-Time) symmetry and structured light in both linear and nonlinear regimes. The PIs will conduct basic theoretical studies, numerical modeling and design, fabrication, and characterization of the PT synthetic structures to facilitate efficient linear and nonlinear strategies to manipulate optical modes and enhance novel spin and orbital light-matter interactions using nanostructured PT synthetic materials. In particular, they will apply the theoretical framework based on the optical transfer matrix to determine the required conditions for simultaneously realizing lasing and its time reversal - antilasing (coherent perfect absorption). They will also use this technique in their designs to experimentally demonstrate an efficient strategy of controlling light with light and the manipulation of photons between two opposite states at low pump intensities. In addition, they will exploit the properties PT exceptional points, which facilitate the unidirectional light transport and accidental mode degeneracy, to enhance the photonic spin-orbit coupling. Finally, the PIs will apply optical nonlinearities to induce PT phase transition crossing over the PT exceptional points, which facilitates enhanced Berry phase and the effective manipulation of the trajectory of light through the related photonic spin-Hall effect.
