    Abstract: In a method of manufacturing a photonic integrated circuit having a compound semiconductor structure having a quantum well region, the structure is irradiated using a source of photons to generate defects, the photons having energy (E) at least that of the displacement energy (ED) of at least one element of the compound semiconductor. The structure is subsequently annealed to promote quantum well intermixing. The preferred radiation source is a plasma generated using an electron cyclotron resonance (ECR) system. The structure can be masked in a differential manner to selectively intermix the structure in a spatially controlled manner by controlling the exposure portions of the structure to the source of radiation.

    Abstract: A silicon-photonic integrated circuit comprising a direct-bandgap-semiconductor-based active optical device that is epitaxially grown on an indirect-bandgap SOI substrate (108) is disclosed. The structure of the active optical device includes an active region (120) having quantum dots (206) made of InGaAs that are embedded in one or more confinement layers (n-InP, p-InP), where the bandgap of the confinement layers is higher than that of the quantum dots. Further the confinement-layer material is preferably lattice matched to the quantom dot material in order to supress associated crystalline defects within the material are located away from the center of its bandgap such that they suppress recombination-enhanced defect-reaction-driven degradation of the active optical device. The active optical device is epitaxially grown on a handle substrate of an SOI substrate that has a surface waveguide formed in its device layer, where the active region and the surface waveguide are at the same height above the handle wafer surface.

    Abstract: A method for producing an integrated optical circuit comprising an active device and a passive waveguide circuit includes: applying an active waveguide structure on a source wafer substrate; exposing a portion of the source wafer substrate by selectively removing the active waveguide structure; applying a passive waveguide structure on the exposed portion of the source wafer substrate, wherein an aggregation of the active waveguide structure and the passive waveguide structure forms the active device, the active device having a bottom surface facing the source wafer substrate; removing the source wafer substrate from the active device; and attaching the active device to a target substrate comprising the passive waveguide circuit such that the bottom surface of the active device faces the target substrate.
