Abstract
An apparatus for providing electrooptic modulation. The apparatus includes electrical contacts, a waveguide coupled between the electrical contacts, and a nonlinear optical material positioned in the slot region. The waveguide includes a first arm and a second arm that are each arranged to define a slot region for confining an optical mode. The slot region has a height, t1, and each of the first arm and the second arm include a strip load region having a height that is less than the height, t1, of the slot region. Each of the first arm and the second arm is configured to provide an electrical signal to the slot region via at least one of the electrical contacts. In one embodiment, the nonlinear optical material includes a χ2-based material. In another embodiment, each of the first arm and the second arm have an “L”-type shape.
