Abstract (in Japanese) (See Japanese page) 
(in English) An all-optical switch using saturable absorption that accompanies refractive-index change such as in graphene films is proposed. The switching conditions are theoretically derived for arbitrary values of absorption and refractive-index change. It is found that switching can be performed by weaker control light when the refractive-index change is accompanied in saturable absorption. Switching conditions for various combinations of absorption and refractive-index change are confirmed by FD-BPM simulation. The saturable absorption and refractive-index change in multi-layered graphene sheets are also discussed based on reported experimental results.
