Applications of Non-Linear Optics.

Abstract

Spatial mode-multiplexing is used to transmit several communication channels on a single multimode optical fiber. Each channel is encoded by an orthogonal pattern produced by a spatial light modulator. A photorefractive medium holographically decodes the output speckle pattern at a receiver station. A ring and star architectures for interconnection networks is demonstrated. Typical crosstalk to signal ratios, for fully interconnected 3 processor networks, are -24 and -26 dB for the ring and star respectively. Keywords: Fiber optics; Optical communications.
