Abstract
Provided is an optical switch including a substrate, a first optical waveguide disposed on the substrate and having a conductive portion disposed on one surface thereof, and a second optical waveguide disposed on the substrate being spaced apart from the first optical waveguide and having an electrode portion disposed on one surface thereof. The electrode portion and the conductive portion face each other. The electrode portion controls an optical field between the first optical waveguide and the second optical waveguide.
Claims17
An optical switch comprising:
- a substrate;
- a first optical waveguide disposed on the substrate and having a conductive portion disposed on one surface thereof;
- and
- a second optical waveguide disposed on the substrate and spaced apart from the first optical waveguide and having an electrode portion that is a doped portion of the waveguide,
- wherein the electrode portion and the conductive portion face each other, and the electrode portion controls an optical field between the first optical waveguide and the second optical waveguide, and
- wherein the second waveguide comprises a first side that faces the conductive portion and a second side opposite to the first side, and the second side adjacent to the electrode portion is undoped.
An optical switch comprising:
- a substrate;
- an optical waveguide disposed on the substrate and comprising a first optical waveguide and a second optical waveguide intersecting each other;
- a conductive portion disposed on an intersection of the first optical waveguide and the second optical waveguide;
- an electrode portion disposed on the conductive portion;
- and
- a transparent insulation film disposed between the electrode portion and the conductive portion,
- wherein the electrode portion crosses the intersection of the first optical waveguide and the second optical waveguide, and the electrode portion controls a path of light traveling the first optical waveguide and the second optical waveguide.
