Abstract

In this work we design and build an optoelectronic demultiplexer to distribute audio and video signals transmitted through an optical carrier toward different users using a liquid crystal display (LCD) as a router. The output plane of our proposed device is located within the Fresnel Diffraction regime. With this feature we obtain a simultaneous distribution, high-speed of processing, easiness of path reconfigurations and a high density of interconnections. The optical carrier modulation includes a Frequency Shift Keying signal (FSK) to indicate the interconnection path. This last control signal is manipulated with a personal computer. We present some preliminary results of the feasibility of our proposal.
