Real-time parallel optical logic operation using photorefractive two-wave mixing and fringe-shifting techniques.
The coupling effect between phase and intensity in photorefractive two-wave mixing in a Bi(12)SiO(20) crystal is demonstrated. By using interference fringe-shifting techniques that are executed by a Mach-Zehnder interferometer, an optical parallel logic operation system that is based on the coupling effect is implemented.
