Abstract(in English) | A novel nonlinear directional coupler,whose waveguide cores are assumed to have a self-focusing or self-defocusing nonlinear material and incorporates a grating to assist the process of all- optical switching,is proposed to improve switching characteristics. Its optical switching characteristics are analyzed by using the coupled-mode theory.It is presented that the characteristics of optical switching in the grating-assisted nonlinear directional coupler are better than that of a conventional nonlinear directional coupler consisting of uniform symmetric coupled waveguides.That is,the critical power of the grating-assisted nonlinear directional coupler is smaller than the conventional nonlinear directional coupler.In addition,the effects of loss on the characteristics of grating-assisted nonlinear directional coupler are examined. |
