Abstract
An optical device includes a waveguide configured to guide light, a taper integrated with the waveguide on a substrate configured for optical coupling, and an attenuator to degrade unwanted optical signal from the taper. The attenuator extends along one side of the taper, and includes one of a conductive structure, a doped structure and a refractive structure.
