Abstract: Embodiments include a fiber to photonic chip coupling system including a collimating lens which collimate a light transmitted from a light source and an optical grating including a plurality of grating sections. The system also includes an optical dispersion element which separates the collimated light from the collimating lens into a plurality of light beams and direct each of the plurality of light beams to a respective section of the plurality of grating sections. Each light beam in the plurality of light beams is diffracted from the optical dispersion element at a different wavelength a light beam of the plurality of light beams is directed to a respective section of the plurality of grating sections at a respective incidence angle based on the wavelength of the light beam of the plurality of light beams to provide optimum grating coupling.

Abstract: The optical devices described herein include a lens arrangement for coupling light between light sources and optical fibers with a reduced size compared to the use of optical waveguides, while also allowing for the use of power sensitive optical components, such as components with lower power density configurations. The lens arrangements include a collimating lens, a focusing lens, and at least one optical component positioned between the collimating lens and the focusing lens.

Abstract: Embodiments herein include an optical system that passively aligns a fiber array connector (FAC) to a waveguide in a photonic chip. A substrate of the FAC is machined or etched to include multiple grooves along a common axis or plane to hold optical waveguides, or more specifically, the fibers of the optical cables in the FAC. To align the fibers to the photonic chip, one of the fibers is disposed in an alignment trench which has a width that is substantially the same as the diameter of the fiber. When the fiber registers with the alignment trench, the fiber is aligned with a waveguide disposed at the end of the trench. Because the pitch between the fibers can be precisely controlled, aligning one of the fibers using the alignment trench results in the other fibers becoming passively aligned to respective waveguides in the photonic chip.

Abstract: Embodiments herein describe optical devices that include focusing elements in or on a substrate on which a laser source is disposed. That is, the focusing element can be arranged on a same surface of the substrate as the laser source. In one embodiment, the laser source emits an optical signal that is parallel with the same surface of the substrate. A turning mirror can be used to direct the optical signal in a direction perpendicular to the surface so that the optical signal is incident on the focusing element.

Abstract: An apparatus includes a ribbon, an optical waveguide, and an IC. The ribbon includes a first end. The optical waveguide is disposed within the ribbon and terminates at the first end. The IC includes a curved surface. The first end of the ribbon bends to mate with the curved surface such that the optical waveguide is optically coupled to a corresponding waveguide in the IC.
