21 October 1994 Two-wave mixing in Fe:LiNbO3 waveguide and its application
Author Affiliations +
Photorefractive Fe:LiNbO3 waveguides have been fabricated from Fe: LiNbO3 substrates by proton-exchange. Holographic method was used to measure the light-induce refractive index change in the waveguides and the result mdicated that the waveguides have higher sensitivity and larger index change than pure LiNbO3 waveguides. Optical amplification has been achieved through two-wave mixing and amplification rate up to 200 was obtained.
