Optical NOR gate using cesium vapor.
The transmission of light at the S((1/2))-P((1/2)) resonance in an alkali vapor is strongly dependent on the laser polarization. This polarization dependence can cause a nonlinear interaction between different lasers so that one laser can be used to control the transmission of another laser. An optical NOR gate is demonstrated by using this nonlinearity in a cesium vapor cell.
