Abstract: An optical structure includes a substrate for receiving an optical device. The substrate may hold waveguide reference surfaces for vertical alignment of the device to a waveguide core of the substrate. A carrier for holding the optical device has contact surface parts for holding the optical device and for mounting the carrier to an optical device receiving substrate.

Abstract: The present invention relates to an assembly structure and a method for assembling active and passive photonic and/or optoelectronic devices on a silicon board. The invention relates in particular to an assembly structure and a method for aligning the photonic devices during the assembling procedure. According to the present invention, the assembly structure comprises one or more alignment features comprising tapered side surface parts in directions at least substantially parallel to an optical axis. By providing a tapering in a direction in a direction at least substantially parallel to the first optical axis, any inaccuracies primarily affects the non-critical positioning in the direction along the optical axis, whereas the critical positioning transverse to the optical axis merely depends on the symmetry of alignment features. The errors from the inherent inaccuracy of the position and shape of alignment features are thereby minimized.
