An investigation of optical switching in phase-shifted metal–semiconductor–metal Bragg gratings is presented. A silicon-on-insulator waveguide with aluminum interdigitated surface gratings and an amorphous silicon overcoat provided high-contrast, tunable switching characteristics. This structure is one of many potential realizations of a novel class of metal–semiconductor switching devices currently under investigation. We discuss switching dynamics, tuning mechanisms, and potential applications.
