Electrooptic nonlinear Fabry-Perot devices

A Fabry-Perot resonator containing an electrooptic element driven by the transmitted light can be used for a number of light processing operations. We describe the use of such devices for pulse Shaping, optical limiter, and optical logic applications. "Optical triode" operation is demonstrated. We also propose and demonstrate a new type of "high-nonlinearity" operation which permits multilevel optical logic and switching operations.
