The transmission process through the system is investigated quantitatively by the coupling and transmission efficiencies, and an optical switch effect is found as the antenna length varies. To understand the physical mechanism, we then investigate the electrical field distribution of the antenna over a rectangle aperture as a simplified model. It is discovered that the "on" state of the system is due to Fabry-Perot resonances in the horizontal cavity formed by antenna, dielectric layer, and metal film. On the other hand, a cutoff occurs for the characteristic rectangle length shorter than the diffraction limit to turn the device to the "off" state. Such a phenomenon can thus provide a promising candidate for application in manipulating light in large-scale optoelectronic device integration.
