Tunable polarization-controlled perfect switching of transverse scattering
Abstract:
We demonstrate the polarization-controlled perfect switching effect in near-infrared frequency ranges using silicon particles embedded in a liquid crystal cell. The effect has electric field tunable properties in a wide frequency band. The phenomenon originates from the interaction between electric multipole modes and magnetic multipole modes, which can also be generalized to the visible and other frequency ranges. It is expected that such an electric field tunable switching device can play important role in the optical information process.

Biasing of P-N Junction
In equilibrium, no external voltage is applied across the p-n junction. The depletion region is formed at the junction interface due to the diffusion of carriers, which leaves behind charged dopants, acceptors on the p-side, and donors on the n-side. These immobile charges create an electric field that prevents further diffusion of carriers. The related energy band...
