Abstract: Techniques for forming a facet optical coupler to couple light at an edge of silicon substrate are described. The facet optical coupler includes a silicon substrate, a layer of second material disposed on the silicon substrate and in direct contact with the edge of the silicon substrate, and an undercut region disposed between a portion of the silicon substrate and the layer of second material. The undercut region is offset from the edge to provide mechanical integrity of the facet optical coupler to improve production of photonic integrated circuits having the facet optical coupler from a wafer.

Abstract: An optical coupling system includes a tapered coupling element having a first end opposite a second end, a core having a core diameter that is larger at the first end than at the second end, and a cladding layer that is coupled to and circumscribes the core. An optical pathway is disposed within the core and that extends between the first end and the second end. The tapered coupling element is tapered from the first end to the second end such that the core diameter adiabatically transitions a light beam traveling along the optical pathway from a first beam size at the first end to a second beam size at the second end.

Abstract: An optical device is provided for coupling an external optical signal into a plurality of on-chip photonic sub-circuits provided on a substrate. The optical device comprises: a planar waveguide layer on the substrate; a diverging grating coupler configured to couple the external optical signal to the planar waveguide layer and to thereby create an on-chip diverging optical beam in the planar waveguide layer; and a plurality of channel waveguides formed in the waveguide layer. Each channel waveguide of the plurality of channel waveguides comprises a waveguide transition structure having a waveguide aperture oriented towards the diverging grating coupler. For each channel waveguide of the plurality of channel waveguides the position and the width of the corresponding waveguide aperture and the angle and the shape of the waveguide transition structure are individually selected to capture a predetermined portion of the on-chip diverging optical beam.

Abstract: A monolithic optoelectronic device has a spot-size converter optically connected to a waveguide. The overclad extending over the core of the waveguide is thinner and differently doped than the overclad of the spot-size converter. This structure can be made by applying a process of etching and enhanced selective area regrowth to create regions of the overclad of different thickness or doping. The spot-size converter core is made of a different material than the waveguide core by using etching and enhanced selective area regrowth.

Abstract: A photonic waveguide structure may include a tapered photonic waveguide structure within a photonic substrate, such that the tapered photonic waveguide structure has a tapered region that progressively tapers in width along a longitudinal length of the tapered photonic waveguide structure. The photonic waveguide structure also includes an optical fiber waveguide having a core region and a cladding region, whereby a portion of the core region is partially exposed by removing a portion of the cladding region. An outer surface of the portion of the core region that is partially exposed is substantially coupled to the tapered photonic waveguide structure. An optical signal propagating along the tapered photonic waveguide structure is coupled from the tapered region of the tapered photonic waveguide structure to the core region of the optical fiber waveguide via the core region that is partially exposed.
