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: A system includes an optical source, an integrated circuit, an optical fiber, and a polarization controller. The optical source is arranged emit an optical signal. The integrated circuit includes a mirror. The optical fiber carries the optical signal from the optical source to the integrated circuit. The mirror reflects a transverse magnetic component of the optical signal through the optical fiber to the optical source. The polarization controller adjusts, based on the transverse magnetic component, the optical signal emitted from the optical source such that the transverse magnetic component is reduced.

Abstract: An optical coupling may involve orienting a waveguide and a lens such that light rays are focused on a surface. The lens may involve the use of a material having a variable refractive index to focus rays of light along first axis and a curved surface to focus the rays of light along a second axis.

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.
