    Abstract: A method includes providing a semiconductor wafer that includes at least one optical waveguide extending in a longitudinal direction. Stealth dicing laser processing is applied to the semiconductor wafer by producing defect regions into the wafer along at least one cutting line. The cutting line is oblique to the longitudinal direction of the at least one optical waveguide. The wafer is expanded to induce fracture thereof at the at least one cutting line, thereby producing an end surface of the at least one optical waveguide. The end surface is oblique to the longitudinal direction of the at least one optical waveguide.

    Abstract: An optical coupling includes a body having a first surface which couples with a photonics integrated circuit and a second surface including an array of lenses integral with the body. The array of lenses couples to an optical fiber connector. The array of lenses may be a linear array. The body may be made of a polymer material, which may be optically cured. The photonics integrated circuit and the optical coupling may be used, for example, in a mobile phone. The optical coupling may be made by shaping curable material on a photonics integrated circuit into a body, and curing the body of curable material. The cured body includes the first surface in contact with the photonics integrated circuit and the second surface including the array of optical lenses to couple with the optical fiber connector.

    Abstract: An embodiment apparatus comprises an optically transparent substrate having first and second surfaces; a piezoelectric membrane, arranged at the first surface, that oscillates in response to a light beam propagated through the substrate; at least one reflective facet facing the substrate and arranged at the piezoelectric membrane; and an optical element receiving the light beam at an input end and guiding the light beam towards an output end coupled to the second surface. The optical element incorporates a light focusing path focusing the light beam at a focal point at the piezoelectric membrane, and at least one light collimating path collimating the light beam onto the at least one reflective facet. The optical element guides light reflected from the at least one reflective facet to the input end, the reflected light indicating a position of the optical element with respect to the focal point.

    Abstract: A method includes providing a semiconductor body comprising a surface with a recessed portion therein. The recessed portion includes a bottom surface. Optical waveguide cores in a first array of optical waveguide cores extend side-by-side at the bottom surface. The method further includes providing a second array of optical waveguide cores over the first array of optical waveguide cores. Optical waveguide cores in the second array of optical waveguide cores extend side-by-side. Each optical waveguide core in the second array of optical waveguide cores is in an adiabatic coupling relationship with a corresponding optical waveguide core in the first array of optical waveguide cores. The method also includes applying an optical waveguide cladding material over the second array of optical waveguide cores.
