In this study, new designs not using electronic circuits are suggested for an optical vector multiplier to achieve optical interconnections. Nonlinear optical devices using photorefractive four-wave mixing are employed as the core device. If optical interconnection can be directly controlled by light, self-routing at an optical ATM can be realized without using electronic circuits. It is highly advantageous for suppression of heating or achieving high density interconnection. The concepts and optical designs of an all-optical interconnection and a self-routing system are presented here and basic operations in experimentation are examined.
