heal.abstract	Proton exchanged LiNbO3 waveguides are studied using Raman spectroscopy. Depending on the waveguide mode, the spectra resemble those of pure LiNbO3 at high temperatures. A characteristic peak appears at 69 cm-1 which is probably due to second-order Raman scattering but strongly associated with the presence of protons. It is proposed that the change in the Raman spectra is due to the coexistence of the ferroelectric and paraelectric phases of LiNbO3 at room temperature, induced by the proton exchange deformations on the lattice.	en
