| Abstract: | A polarization splitter is proposed and numerically investigated. It is composed of two same structures with different arrangement, which is a kind of metal-dielectric nanocavity filling a piece of nonlinear optical material into metal gap waveguides for each. This device with optical bistability based on surface plasmon provides a new way to manipulate light by tuning the incident light intensity and will be essential for the coming optical information processes. |
