Abstract
A coupling interface arrangement is described for a photonic integrated circuit (PIC) device. The PIC includes an interface coupling surface having optical grating elements arranged to form optical output locations that produce corresponding light output beams. A coupling lens couples the light output beams into a conjugate plane at a far-field scene characterized by one or more optical aberrations that degrade optical resolution of the light outputs. The optical grating elements are configured to correct for the one or more optical aberrations.
