Abstract
An optical device includes a waveguide on a base and a taper on the base. The waveguide and the taper are optically aligned such that the taper and the waveguide exchange light signals during operation of the device. The taper is configured to guide the light signals through a taper material and the waveguide is configured to guide the light signals through a waveguide medium. The taper material and the waveguide medium are different materials and/or have different indices of refraction.
