Abstract: A laser array includes a plurality of laser diodes arranged and electrically connected to one another on a surface of a non-native substrate. Respective laser diodes of the plurality of laser diodes have different orientations relative to one another on the surface of the non-native substrate.

Abstract: A semiconductor device includes a detector structure. The detector structure includes an integrated circuit on a substrate, and a photo detector on an upper surface of the integrated circuit that is opposite the substrate, where the substrate is non-native to the photo detector. A System-on-Chip apparatus includes at least one laser emitter on a non-native substrate, at least one photo detector on the non-native substrate, and an input/output circuit. The at least one photo detector of the second plurality of photo detectors is disposed on an integrated circuit between the at least one photo detector and the non-native substrate to form a detector structure.
