Abstract

The operation of the bridge mutually pumped phase conjugator is reported in a planar waveguide structure in photorefractive BaTiO₃. The waveguide was fabricated by the technique of ion implantation, using 1.5-MeV H⁺ ions at a dose of 10¹⁶ ions/cm². An order of magnitude decrease in response time is observed in the waveguide as compared with typical values obtained in bulk crystals, probably as a result of a combination of the optical confinement within the waveguide and possible modification of the charge-transport properties induced by the implantation process.
