Abstract
An optical system is provided including a photonic integrated circuit and an optical lens system. The photonic integrated circuit includes an emission interface surface and a spatial array of apertures. The spatial array of apertures has a high numerical aperture (NA) of greater than 0.2 and includes a plurality of apertures spatially distributed across the interface surface. The optical lens system interfaces the photonic integrated circuit with free space by: receiving emitted light from the spatial array of apertures and altering a trajectory of the emitted light into the free space and receiving returning light from the free space and altering a trajectory of the returning light, such that the returning light is received by the spatial array of apertures.
