We propose and numerically simulate a nanoscale electro-optic (EO) switch based on a metal-insulator-metal structure composed of a strip waveguide and two side-coupled cavities filled with an EO material of 4-dimethylamino-N-methyl-4-stilbazolium tosylate,using the finite difference time domain method.It is found that the structure can be operated as an EO switch at a wavelength of 945nm,with a modulation depth of 27dB,a half-wave voltage of 5.3 V and a switching time of about 50 ps.
