Abstract: Some embodiments of the present disclosure describe an apparatus for III/V-Si taper coupling, including a III/V-Si taper coupler with one end to receive a laser beam where the one end has at least one surface at a non-perpendicular angle with respect to a direction of the laser beam, and where the at least one surface forms one or more tips at the one end of the III/V-Si taper coupler. The one end is positioned so that the one or more tips are outside the laser beam to reduce reflection of laser beam away from the one end of the III/V-Si taper coupler.

Abstract: Apparatuses, methods and storage medium associated with an optical iso-modulator are disclosed herein. In embodiments, an apparatus may include an optical waveguide formed on one or more layers, such as an isolation layer and a handling layer. A modulator driver may be coupled to a first side of the one or more layers. A magneto-optical (MO) die may be coupled to a second side of the one or more layers that is opposite the first side. Other embodiments may be disclosed and/or claimed.
