Abstract
This disclosure relates to the layout of optical components included in a photonics integrated circuit (PIC) and the routing of optical traces between the optical components. The optical components can include light sources, a detector array, and a combiner. The optical components can be located in different regions of a substrate of the PIC, where the regions may include one or more types of active optical components, but also may exclude other types of active optical components. The optical traces can include a first plurality of optical traces for routing signals between light sources and a detector array, where the first plurality of optical traces can be located in an outer region of the substrate. The optical traces can also include a second plurality of optical traces for routing signals between the light sources and a combiner, where the second plurality of optical traces can be located in regions between banks of the light sources.
