title: All-optical switching by use of cascading of phase-matched sum-frequency-generation and difference-frequency-generation processes in periodically poled LiNbO(3).
abstract: We show that all-optical switching is feasible by means of cascading of sum-frequency-generation and difference-frequency-generation processes under phase-matched conditions. Three-terminal switching is demonstrated experimentally with bulk periodically poled LiNbO(3). The cascading under phase-matched conditions facilitates switching with lower power than that required under phase-mismatched conditions.
