Abstract
An electro-optic light modulator design based on a grating-coupled surface-plasmon-resonance structure is numerically investigated using finite-difference time-domain simulation. The thickness effect of a dielectric layer acting as a waveguide on metal structures is investigated. The results show that the new structure has much higher modulation index than the conventional one and can implement an electro-optic modulator with low operating voltage.
