An optical interposer comprising an array of first order diffraction grating couplers arranged to couple light emitted by an array of single mode Vertical-Cavity Surface-Emitting Lasers (VCSELs) into optical waveguides, the light being emitted in a direction substantially perpendicular to the optical waveguides; a device for refracting the light over at least 4 degrees; an array of output ports arranged to optically couple light from the optical waveguides into an array of optical fibers or other optical elements; and the optical waveguides connecting the array of first order diffraction grating couplers and the array of output ports to route the light from the diffraction gratings into the output ports.

Optical interposer

The present invention provides an assembly () of integrated optical components and methods of producing thereof wherein the assembly () of optically linked optical components comprises a motherboard () having one or more primary lateral reference features () and a sub-assembly () comprising an optical component () mounted on a daughterboard (), said sub-assembly () having one or more secondary lateral reference features (). The primary lateral reference features may be optical alignment features. The daughterboard () may be mounted on the motherboard () such that the optical component () may extend into a motherboard recess (). The lateral alignment of the component () with the motherboard () is provided by aligning the primary () and secondary lateral reference features (). The daughterboard () may further comprise tertiary lateral reference features () which in combination with the secondary lateral reference featuresform a self correcting alignment system.
