Abstract
An optical correlator ( ) that uses a spatial light modulator ( ) to illuminate a pattern of on and off pixels into a length of an optical fiber ( ). The spatial light modulator ( ) is optically coupled to the length of fiber ( ) so that the illumination enters the fiber along that length. The optical fiber ( ) also carries light representing a bitstream of data. At the optical fiber, the illumination from the spatial light modulator interacts with the illumination of the optical bitstream. A detector ( ) is optically coupled to the same length of fiber ( ) and detects the resulting optical response to determine if a correlation exists.
