Abstract
The invention provides an optical switch that consumes a less power, excels in a high-speed response, and possesses a structure suitable for a miniaturization and multi-channel switching. The optical switch switches a plurality of input signals to a plurality of output positions, in which a laminated structure that has a nonlinear optical layer and a buffer layer laminated in the same number as that of input parts intersects an optical path between the input parts and output parts. By providing the laminated structure using the nonlinear optical thin films, the invention achieves a small matrix optical switch excellent in a high-speed response and suitable for switching a large-capacity of information.
