Two-wave mixing at 854 nm in BaTiO3:Rh planar waveguide implanted with He+

2001

Abstract Guided waves at 854 nm are observed in a BaTiO 3 :Rh waveguide fabricated by the technique of ion-beam implantation. The photorefractive interaction between two guided modes is demonstrated and characterized. The experiments reveal that the gain direction is reversed in the guiding layer in comparison with that in the bulk. A maximum gain of 24 cm −1 is achieved.

Self-pumped phase conjugation in a BaTiO3:Rh waveguide

2002

We present a self-pumped phase conjugator originated by self-bending of the incident beam at λ = 515 nm in a BaTiO3:Rh waveguide elaborated by three successive He+ ion implantations. Phase conjugate reflectivity reached is 28 %.
