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 10):
A method for coupling light between a photonic chip and an optical fiber, comprising:\n emitting X and Y component beams by first and second surface grating couplers (SGCs), respectively, wherein the first and second SGCs are orthogonally disposed on the photonic chip at the first and second locations and are configured for coupling a same polarization mode from the photonic chip; combining the X and Y component beams into a beam of light; and re-focusing the beam of light onto the optical fiber.
