Abstract

A light detection and ranging (LIDAR) device includes a waveguide, cladding, and a scattering array. The waveguide is configured to route an infrared optical field. The cladding is disposed around the waveguide. The scattering array is formed in the cladding. The scattering array is configured to perturb the infrared optical field routed by the waveguide to direct the infrared optical field into an infrared beam propagating toward a surface of the cladding.
