Abstract

We demonstrate an all-optical control device based on a structure with nonlinear core layer containing dye-sensitized liquid crystal. We study the signal field coupled out the cladding surface and observe an interesting polarization rotation effect due to the coupling of two different nonlinear dynamics in the nonlinear optical layer. This unique polarization rotation effect allows us to build a compact and low-cost all-optical switching device.
