Abstract

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 10¹⁶ ions/cm². 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.
