The use of refractive index data for studying changes in oriented polyolefin films has been demonstrated. Application of this technique to oriented polypropylene and polyethylene films showed that the birefringence is a linear function of the refractive index in the direction of maximum orientation.

## 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
