Abstract

Erbium is doped into z-cut Lithium Niobate (LiNbO₃) substrate by thermal diffusion from thin Er film. XPS, PL and reflection studies have been carried out in order to characterize the doped sample and to test the suitability for amplifying signal at the wavelength 1530 nm. Straight waveguides of different widths (10, 15 and 100 micrometer) have been fabricated on the Er-doped sample by Ti diffusion. Loss measurements for the Er:Ti:LiNbO₃ waveguides have been done by using lasers of wavelengths 633 and 1300 nm.
