ABSTRACT:
An optical mode transformer. The optical mode transformer features a low index core, a high index core having a first tapered region, with the high index core embedded within the low index core and with the low index core serving as a cladding for a waveguide defined by the high index core embedded in the low index core, and a cladding layer surrounding the low index core, with the cladding layer including one or more materials with different refractive indices than those of the low index core and high index core.
