    Abstract: A method of fabricating a composite integrated optical device includes providing a substrate comprising a silicon layer, forming a waveguide in the silicon layer, and forming a layer comprising a metal material coupled to the silicon layer. The method also includes providing an optical detector, forming a metal-assisted bond between the metal material and a first portion of the optical detector, forming a direct semiconductor-semiconductor bond between the waveguide, and a second portion of the optical detector.

    Abstract: A method of fabricating a gain medium includes growing a p-type layer doped with zinc on a substrate, growing an undoped layer including one or both of InP or InGaAsP on the p-type layer, growing a region that includes multiple quantum wells (MQWs) on the undoped layer, and growing an n-type layer on the region. The undoped layer has a thickness that is sufficient to prevent Zn diffusion from the p-type layer into the region during subsequent growth or wafer fabrication steps.

    Abstract: An exemplary multi quantum well structure may include a silicon platform having a pit formed in the silicon platform, a chip positioned inside the pit, a first waveguide formed in the chip, and a second waveguide formed in the silicon platform. The pit may be defined at least in part by a sidewall and a base. The chip may include a first side and a first recess in the first side. The first side may be defined in part by a first cleaved or diced facet. The first recess may be defined in part by a first etched facet. The first waveguide may be configured to guide an optical beam to pass through the first etched facet. The second waveguide may be configured to guide the optical beam to pass through the sidewall. The second waveguide may be optically aligned with the first waveguide.

    Abstract: A method is provided for forming an optical device having a waveguide and a spot size converter (SSC). The method includes providing a crystalline semiconductor region and a non-crystalline semiconductor region on a substrate. The crystalline semiconductor region is coupled to the non-crystalline semiconductor region. The method also includes simultaneously etching the non-crystalline semiconductor region and the crystalline semiconductor region using a same etch mask to form a spot size converter coupled a waveguide. The waveguide has a ridge over a shoulder, and the spot size converter has a ridge over a shoulder.
