Abstract

Optical Kerr effect were applied to an all-optical switching device in the form of nonlinear waveguide directional couplers. The nonlinear directional coupler had a nonsymmetrical waveguide whose structure consists of a quartz thin gap between two Corning 7059 guided layers on the pyrex substrate with ion-milled grating and organic thin film as a top layer. The vacuum-deposited polydioacetylene film was used as an organic nonlinear material. Switching phenomena in this nonlinear directional coupler were confirmed for 10 ns pulse Nd:YAG laser and 150 fs pulse duration of mode-locked Ti:Sapphire laser.
