BaTiO3 waveguide self-pumped phase conjugator

By S.W. James, K.E. Youden, P.M. Jeffrey, R.W. Eason, P.J. Chandler, L. Zhang and P.D. Townsend


For the first time to our knowledge, self-pumped phase conjugation is reported in a planar waveguide structure in a BaTiO3 single crystal. The waveguide was fabricated by the technique of ion implantation, with 1.5-MeV H+ ions at a dose of 10^16 ions/cm^2. Phase-conjugate reflectivities >20% have been measured for waveguide self-pumped phase conjugation, and, for a given input power, an order-of-magnitude reduction in the response time is observed in the waveguide compared with the bulk. The fidelity of phase conjugation in the guide is also discussed
