Universal building blocks for modular photonics and related all-optical technologies

"The goal of the present Phase 1 proposal is introducing nonlinear optical technologies for controlling light beams in complex optical structures, including fiber optics interconnects and switches. We will revisit and gain further insight into the processesof laser beam interaction with liquid crystals proving that novel materials have matured those processes for modern applications. Operation of a diversity of new generation photonics devices will be tested in order to demonstrate the depth of the potentialimpact of new nonlinear optical materials and processes on photonics. Among them are Nonlinear Optical Cubes as universal building blocks for all-optical logic gates, interconnects, switches, scanners, and limiters. Liquid Crystal Streak Cameras willvisualize optical trajectories in complex optical structures like tapered and bent fibers. They will also make possible on-line measurement of intrafiber light radiation, control with its power, polarization and mode structure. Optical and mechanicalproperties of liquid crystals will be used for demonstration of such unique phenomena as Optically Controlled Optical Bistability and non-reciprocal light propagation. New nonlinear optical materials will be synthesized specifically for controlling nearand mid IR beams using the opportunities provided by the synthetic versatility of liquid crystal systems. Modular Photonics and new opportunities for all-optical light manipulations will simpl
