Simultaneous all-optical logical operations using the third order nonlinear optical effect and a single waveguide

摘要

Spatial modulation representing digital information is imposed on a pump laser beam, and differing modulation representing different digital information is imposed on a second light beam which has a frequency equal to the pump beam less the nonlinear optical Stokes frequency shift. All the digital information on the two beams is logically combined simultaneously in a single waveguide containing the corresponding nonlinear optical (e.g. Brillouin) material with the result of the logical operations recorded on the wavefront of the second light beam.
