Abstract
An electro-optic device is described. The electro-optic device includes a ridge waveguide and a channel waveguide. The ridge waveguide includes a first portion of at least one electro-optic material. The first portion of the electro-optic material(s) includes a slab and a ridge on the slab. The ridge has a ridge height. The slab has a slab height less than the ridge height. The channel waveguide is optically coupled with the ridge waveguide and includes a second portion of the electro-optic material(s). The channel waveguide has a channel height less than the slab height.
