Abstract
The reverse proton-exchange (RPE) process performed in different crystalline phases of proton-exchanged and annealed proton-exchanged waveguides leads to remarkable optical and compositional modifications. Analysis of ordinary and extraordinary index profiles, correlated with concentration depth profiles in RPE samples subjected to different exchange and postexchange treatments, shows how buried-index optical waveguides in with symmetric mode and reduced fiber–waveguide coupling losses can be realized.
