    Abstract: Various embodiments of the present disclosure are directed towards a semiconductor package comprising optically coupled integrated circuit (IC) chips. A first IC chip and a second IC chip overlie a substrate at a center of the substrate. A photonic chip overlies the first and second IC chips and is electrically coupled to the second IC chip. A laser device chip overlies the substrate, adjacent to the photonic chip and the second IC chip, at a periphery of the substrate. The photonic chip is configured to modulate a laser beam from the laser device chip in accordance with an electrical signal from the second IC chip and to provide the modulated laser beam to the first IC chip. This facilitates optical communication between the first IC chip to the second IC chip. Various embodiments of the present disclosure are further directed towards simultaneously aligning and bonding constituents of the semiconductor package.

    Abstract: An optical phase-shifting device includes a ribbed waveguide portion on an insulating layer, the waveguide portion having a p-n or p-i-n junction extending in a longitudinal direction and having a height. A pair of slab portions are disposed adjacent the waveguide portion, one on each side of the ribbed waveguide portion and on the insulation layer. The slab portion have higher doping concentrations than the respective doping concentrations in the ribbed waveguide portion. At least a portion of each slab portion has a height increasing with distance from the waveguide portion, with the slab height being smaller than that of the waveguide portion at the junction between the waveguide portion and slab portion. A pair of contact portions are formed adjacent the respective slab portion and further away from the waveguide portion. A portion of each contact portion can also have a height varying with distance from the waveguide portion.

    Abstract: An electro-optic device includes a substrate and a waveguide on the substrate. The waveguide includes a layer stack including a plurality of electro-optic material layers interleaved with a plurality of interlayers and a waveguide core adjacent to the layer stack. The waveguide may include a pair of electrodes in electrical contact with the plurality of electro-optic material layers. The plurality of interlayers maintains a first lattice structure at room temperature and a cryogenic temperature. The plurality of electro-optic material layers maintains a second lattice structure and crystallographic phase at the room temperature and the cryogenic temperature.
