Abstract:
1. An apparatus for dynamic control of light transmission comprising: a photonic crystal waveguide comprising: a substrate; a slab disposed on the substrate; a core in the slab having an input side on a first end of the waveguide and an output side on a second end of the waveguide; two electrically conductive pads disposed onto the slab and adjacent to a portion of the core; a first region of the core between the electrically conductive pads; a second region of the core between the input side of the waveguide and the first region of the core, wherein the second region comprises a gradually increasing group index; and a third region of the core between the first region of the core and the output side of the waveguide, wherein the third region comprises a gradually decreasing group index.
