Abstract:
1. A planar wafer from which a plurality of optical chips are cleaved, each optical chip being configured to perform a corresponding optical function, the wafer including: a first optical chip among the plurality of optical chips, the first optical chip comprising a circuitry for performing the corresponding optical function and a plurality of waveguides; a sacrificial test structure configured to be contacted, controlled, and monitored for testing the optical function of the first optical chip or an adjoining optical chip on the wafer, the sacrificial test structure being arranged on the wafer such that at least a portion of the sacrificial test structure is severed from the first optical chip upon cleaving the first optical chip from the wafer; and a plurality of waveguides that optically couple the circuitry of the first optical chip or an adjoining optical chip to the sacrificial test structure and that are substantially parallel to the plane of the wafer.
