Abstract
A light detection and ranging apparatus (LIDAR) includes an optical source to generate an optical beam and one or more waveguides to steer the optical beam. The one or more waveguides include a first cladding layer having a first refractive index and a second cladding layer disposed below the first cladding layer, the second cladding layer having second refractive indexes including a range of different refractive indexes, wherein the range of different refractive indexes is greater than the first refractive index of the first cladding layer.
