- Abstract
A method is presented whereby the refractive-index profile (RIP) can be reconstructed from sets of effective indexes measured with different mode types and external refractive indexes. Single-mode waveguide RIP characterization can be easily realized using an index-matching liquid at a single wavelength. This method is described and demonstrated via numerical examples and experimental results. The method has the advantages of convenient operation and accurate results for the characterization of graded-index planar waveguides that support both mode types and contain known modal birefringence. © 2005 Wiley Periodicals, Inc.
