LOCALLY MODIFIED WAVEGUIDE TOTAL THICKNESS VARIATION

Abstract: optical waveguides are formed based on measured parameters of an optical substrate. regions for forming one or more optical elements are identified based on these measurements, and inkjet deposition is utilized to deposit a refraction-matched deposition material is applied to one or more identified regions to selectively modify the total thickness variation (ttv) in each such region. prior to or subsequent to the deposition, optical gratings or other optical elements are formed within the adjusted regions.
