Abstract | In this article, the feasibility of a programmable integrated optical grating based on the control of interface charges, and therefore, conductivity of interfaces is explored. This structure is essentially an array waveguide, in which each waveguide has an independent control on its interface conductivity. As we have shown, the effective index of each waveguide is controllable independently, and therefore and relative output phase differences among the waveguides and be programmed. A phase-array-antenna-like analysis enables one to compute the output far field pattern. |
