Abstract
Disclosed is a hybrid waveguide structure, wherein a core or cladding has a hybrid section or “button” of a different optical property such as refractive index from the major portion of the core or cladding, respectively. The hybrid section can be made of a passive material or an electro-optic material. Methods of making a hybrid waveguide structure are also disclosed. These methods include rib-based methods and trench-based methods, and in either of these methods, a temporary filler is used in many instances to incorporate the hybrid section into the hybrid waveguide structure.
