Abstract
A light detection and ranging apparatus (LIDAR) includes at least one waveguide including a first cladding layer having a first refractive index and a second cladding layer having multiple second refractive indexes to expand an optical mode of an optical beam propagating within the waveguide. The second refractive indexes include a gradient of refractive indexes and the first refractive index is less than the second refractive indexes.
