CHARACTERIZATION OF VAPOR DIFFUSED ZN-LITAO3 OPTICAL WAVE-GUIDES Academic Article

abstract

• Diffusion and optical properties of planar waveguides produced in LiTaO3 by a recently developed technique that utilizes Zn diffusion from vapor phase are presented. The waveguides are obtained by 6-h diffusion at temperatures as low as 800C. The results indicate that Zn is a fast diffusant in LiTaO3 and has activation energies that are slightly less than those for Ti diffusion into LiTaO3. The diffusion temperatures for Zn are much lower than the 1150-1200C requires for Ti metal indiffusion. The diffusion coefficient of Zn at 800C, is comparable to that of Ti at 1200C. The resulting waveguides support both ordinary and extraordinary modes of polarization. The low temperature diffusion slows out diffusion and has been shown to be advantageous for making low-loss optical waveguides in LiTaO3. 1988 IEEE.
