All-optical processing by means of vectorial interactions in second-order cascading: novel approaches

Abstract

Based on the tensorial nature of second-order nonlinear susceptibilities, we show how two orthogonal field components at frequency ω can interact by means of the generated second harmonic, with a resulting coherent control of one onto the other. All-optical transistor operation and polarization switching are among the signal functions that can be implemented in properly oriented crystals.
