Abstract

A multi semiconductor device package includes a laser die and a photonics die. The laser die generates light and includes a laser facet that emits light from a light emitting surface. The photonics die modulates light emitted from the laser light emitting surface and includes a device side cavity that exposes an embedded waveguide optically connected with the laser facet. A laser die and photonics die attachment method includes positioning a device side of the laser die relative to a device side of the photonics die, engaging an alignment feature of the photonics die with an alignment feature of the laser die, installing the laser die within a device side recess of photonics die, electrically connecting the laser die with the photonics die, and optically connecting a laser facet of the laser die with an embedded waveguide of the phonics die.
