Abstract

We propose a feasible multipath switch based on the optical bistability with surface plasmon. The switch is controlled by comparing the intensities of TE and TM modes scattering light from the cross-shaped silver structure involving Kerr material in the center. The working wavelength of the switch has a blue shift by reducing the length of a pair of nanorods in the cross-shaped structure due to the scattering of the structure changed. Our structure is easy to implement in practice and has potential applications in all-optical network in the future.
