Abstract
An optical device may include a substrate and vertical-cavity surface-emitting lasers (VCSELs) on the substrate. The optical device may also include a coupling layer over the substrate and that includes optical guides aligned with the VCSELs to guide outputs thereof from a vertical path direction to a lateral path direction. The optical device also includes controllable delay elements, each controllable delay element associated with a respective optical guide, and a controller coupled to the controllable delay elements.
