Abstract: An arrangement for improving adhesive attachment of micro-components in an assembly utilizes a plurality of parallel-disposed slots formed in the top surface of the substrate used to support the micro-components. The slots are used to control the flow and “shape” of an adhesive “dot” so as to quickly and accurately attach a micro-component to the surface of a substrate. The slots are formed (preferably, etched) in the surface of the substrate in a manner that lends itself to reproducible accuracy from one substrate to another. Other slots (“channels”) may be formed in conjunction with the bonding slots so that extraneous adhesive material will flow into these channels and not spread into unwanted areas.

Abstract: Embodiments herein describe a photonic device that includes a germanium photodetector coupled to multiple silicon waveguides. In one embodiment, the silicon waveguides optically couple to a layer of germanium material. In one embodiment, if the germanium material forms a polygon, then a respective silicon waveguide optically couple to each of the corners of the polygon. Each of the plurality of input silicon waveguides may be arranged to transmit light in a direction under the germanium that is offset relative to both sides of the germanium forming the respective corner. In another example, the germanium material may be a circle or ellipse in which case the silicon waveguides terminate at or close to a non-straight, curved surface of the germanium material. As described below, optically coupling the silicon waveguides at a non-straight surface can reduce the distance charge carriers have to travel in the optical detector which can improve bandwidth.

Abstract: An optical modulator may include a lower waveguide, an upper waveguide, and a dielectric layer disposed therebetween. When a voltage potential is created between the lower and upper waveguides, these layers form a silicon-insulator-silicon capacitor (also referred to as SISCAP) guide that provides efficient, high-speed optical modulation of an optical signal passing through the modulator. In one embodiment, at least one of the waveguides includes a respective ridge portion aligned at a charge modulation region which may aid in confining the optical mode laterally (e.g., in the width direction) in the optical modulator. In another embodiment, ridge portions may be formed on both the lower and the upper waveguides. These ridge portions may be aligned in a vertical direction (e.g., a thickness direction) so that ridges overlap which may further improve optical efficiency by centering an optical mode in the charge modulation region.

Abstract: An optical modulator may include a leftmost waveguide, a rightmost waveguide, and a dielectric layer disposed therebetween. In one embodiment, the waveguides may be disposed on the same plane. When a voltage potential is created between the rightmost and leftmost waveguides, these layers form a silicon-insulator-silicon capacitor (also referred to as SISCAP) structure that provides efficient, high-speed optical modulation of an optical signal passing through the modulator. As opposed to a horizontal SISCAP structure where the dielectric layer is disposed between upper and lower waveguides, arranging the dielectric layer between waveguides disposed on the same plane results in a vertical SISCAP structure. In one embodiment, the leftmost and rightmost waveguide are both made from crystalline silicon.

Abstract: Embodiments described herein describe a sub-mount that is etched to include respective cavities with at least two adjacent sides that align optical filters and a mirror. Moreover, the cavities are arranged on the sub-mount such that when the filters and mirror are disposed in the cavities, they align in a manner that enables the performance of a multiplexing or demultiplexing function as part of, for example, a zigzag multiplexer/demultiplexer. In one embodiment, the filters and mirrors are aligned passively rather than actively. The sub-mount may then be placed on a substrate that includes other components of a ROSA or TOSA. In one embodiment, the substrate is also etched to include a cavity two adjacent sides to align the sub-mount so that sub-mount is passively aligned once disposed into the cavity.

Abstract: An optical modulator may include a lower waveguide, an upper waveguide, and a dielectric layer disposed therebetween. In one embodiment, the lower waveguide may include a u-shaped region within an optical mode of the light passing through the optical modulator. By conforming the dielectric layer to the surfaces of the u-shaped region, the amount of area of the dielectric layer within a charge modulation region is increased relative to forming the dielectric layer on a single plane. Folding the dielectric layer in this manner may improve modulation efficiency. In one embodiment, the u-shaped region is formed by using ridge structures that extend from an upper surface of the lower waveguide towards the upper waveguide. To aid in lateral confinement of the optical mode, the dielectric layer may be deposited on one side surface of the ridge structures while a different dielectric material is deposited on the opposite side surface.
