Abstract:
An optical coupling apparatus for coupling an optical fiber to a photonic chip is described. The apparatus includes a collimating microlens for collimating light from the optical fiber; a polarization splitting beam displacer for separating the light collimated by the collimating microlens into orthogonally polarized X and Y component beams; at least one focusing microlens for directing the X and Y component beams separately onto the photonic chip; and first and second surface grating couplers (SGCs) orthogonally disposed on the photonic chip and configured for operation in a same polarization state, for coupling the X and Y component beams, respectively, to the photonic chip.

Claim (Index 12):
An apparatus for coupling light between an optical fiber and a photonic chip, the apparatus comprising:\n a collimator for collimating or re-focusing light from the optical fiber; a beam separator for separating the light into orthogonally polarized X and Y component beams; a beam director for directing the X and Y component beams to separate first and second locations, respectively, on the photonic chip, wherein the beam director is configured for coupling the X and Y component beams to the photonic chip respectively by first and second surface grating couplers (SGCs) orthogonally disposed on the photonic chip at the first and second locations, respectively, and for coupling a same polarization mode to the photonic chip.
