Abstract:
1. A photonic system comprising: a first ridge waveguide configured to transmit one or more electromagnetic waves, each electromagnetic wave having a different wavelength; a photonic crystal including a resonant cavity and configured to selectively and evanescently couple at least one of the one or more of the electromagnetic waves from the first waveguide into the resonant cavity; a second ridge waveguide positioned to transmit and extract one or more electromagnetic waves from the resonant cavity via evanescent coupling, wherein the second ridge waveguide is substantially aligned with the first ridge waveguide, and the resonant cavity is positioned between a first end of the first ridge waveguide and a first end of the second ridge waveguide; and a first electrode disposed adjacent to the photonic crystal and a second electrode positioned on an extended region of the photonic crystal, wherein the first electrode and the second electrode are outside the resonant cavity and are configured to apply a voltage across the resonant cavity in order to modulate the one or more electromagnetic waves transmitted from the first ridge waveguide to the second ridge waveguide.
