Abstract

Photorefractive Fe:LiNbO3 planar waveguides have been fabricated by proton exchange method using Fe:LiNbO3 as substrate and benzoic acid as exchange medium. The waveguide has a much larger refractive index increment than a Ti diffused one. Through end-face coupling, a pump beam and a signal beam were injected into the waveguide and the optical amplification properties of the waveguide have been investigated experimentally. The results showed that a hundred fold amplification gain could be obtained in a wide range of grating periods and an amplification gain of 180 was achieved easily. This scheme has potential applications in optical signal processing at not very high incident intensity.
