Abstract
An electronic/photonic integrated circuit in which grating-outcoupled surface-emitting lasers are used both to provide external emission out of the plane of the chip (through gratings), and also to feed optical power into photonic waveguides parallel to the plane of the chip. Transistors are fabricated in a common multilayer semiconductor body with the lasers.
