Abstract:
1. An apparatus comprising: a package substrate to provide a packaging mount for a photonic transceiver; a semiconductor die including photonic transceiver circuitry, the semiconductor die to be flip-chip bonded to the package substrate, the semiconductor die to overhang the package substrate on an edge of the semiconductor die to be active in an optical mode of the photonic transceiver, the semiconductor die having a groove processed in semiconductor bulk of the semiconductor die to face the package substrate when the semiconductor die is bonded to the package substrate; an alignment pin to contact the semiconductor die at the groove and extend beyond the semiconductor die away from the package substrate to provide passive alignment of the optical mode of the photonic transceiver to an optical lens; and a support to hold the alignment pin to the semiconductor die at the groove.
