Real-time Optical Logic Processors by Two-Wave Mixing in $BaTiO_3$ Crystal
$BaTiO_3$ 결정에서의 두 광파 혼합현상을 이용한 광 논리처리기
Abstract
Nonlinear beam coupling phenomena in photorefractive materials are analyzed as a function of the input beam intensities. Signal beam saturation and pump beam depletion are shown to be the intensity-dependent functions of these materials. Utilizing these phenomena in a photorefractive BaTiO3 crystal, optical logic processors such as AND, OR, NOT, etc., are implemented.
