    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: An optical integrated circuit device includes a semiconductor substrate and a first waveguide made of a first material and disposed over the semiconductor substrate. The first waveguide includes a parallel region and a tapered region. The optical integrated circuit device further includes a first cladding structure disposed over and surrounding the parallel region of the first waveguide, a first extension made of the first material and disposed over the semiconductor substrate, and an electrostatic discharge (ESD) protection structure electrically coupled to the first extension. The first extension physically contacts the parallel region of the first waveguide. The first extension includes a first portion within the first cladding structure and a second portion outside the first cladding structure.

    Abstract: System for coupling light to integrated devices, comprising a grating coupler which couples light, such as light from a light source, into an optic fiber. The system includes an optic subsystem comprising a transmitter portion receiving the light emitted by the grating coupler and a receiver portion receiving light from the transmitter and focusing the light into the integrated device, the transmitter portion being configured to modify an angle distribution of the light emitted by the grating coupler and the receiving portion being configured to focus the light with modified angle distribution into the integrated device.

    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.
