Abstract

In this paper, we present a space division technique to multiplex communication channels in a regular step-index multimode fiber using holographic correlator. We consider a multimode fiber with a large diameter of core as highly scattering medium. Thus, the focusing laser spot at different position on the incident plane of the fiber excites different sets of modes, which gives a different speckle pattern at the output of the fiber. Hence, each focusing spot can be considered as a communication channel for data transmission. By combining the volume holographic techniques to form channel multi/demultiplexer in a transmission system, we demonstrate conceptually transmission of multichannel optical information by using a regular step-index multimode fiber for data transmission application.
