Abstract
An optical device including a waveguide and an electrode is described. The waveguide includes at least one optical material having an electro-optic effect. The electrode includes a channel region and extensions protruding from the channel region. The extensions are closer to a portion of the waveguide than the channel region is.
Claims22
An optical device, comprising:
- a waveguide including at least a portion of at least one optical material having an electro-optic effect, the at least one optical material including at least one of lithium niobate and lithium tantalate;
- and
- an electrode including a channel region and a plurality of extensions protruding from the channel region, the plurality of extensions being closer to a portion of the waveguide than the channel region is, the electrode carrying an electrical signal;
- wherein a microwave mode of the electrical signal carried in the channel region intersects the at least one optical material.

A subassembly, comprising:
- an optical modulator, the optical modulator including a waveguide and an electrode, the waveguide including at least a portion of at least one optical material having an electro-optic effect, the electrode including a channel region and plurality of extensions, the plurality of extensions residing between the channel region and the waveguide, the plurality of extensions being closer to a portion of the waveguide than the channel region is, the electrode carrying an electrical signal, wherein a microwave mode of the electrical signal carried in the channel region intersects the at least one optical material, the at least one optical material including at least one of lithium niobate and lithium tantalate;
- and
- a driver coupled to the optical modulator and configured to electrically drive the electrode.
A method, comprising:
- providing a waveguide including at least a portion of at least one optical material having an electro-optic effect, the at least one optical material including at least one of lithium niobate and lithium tantalate;
- and
- providing an electrode including:
- providing a channel region;
- and
- providing a plurality of extensions protruding from the channel region, the plurality of extensions being closer to a portion of the waveguide than the channel region is, the electrode carrying an electrical signal;
- wherein a microwave mode of the electrical signal carried in the channel region intersects the at least one optical material.
