Abstract

A self-aligning guided wave breadboard system has been developed, based on preferentially etched silicon, which can splice single mode optical fibre ribbon cable, or connect ribbon fibre pigtails to integrated optic chips containing arrays of channel waveguide components. The system can be used to construct optical delay-line signal processing networks with an extremely simple architecture, involving a single I0 chip and multiple fibre links. The processors may be used to encode a low-bandwidth signal before transmission in an optical LAN. The signal may then be decoded using a similar processor acting as a matched filter, allowing instantaneous access to a bus for a number of users through CDMA , or self-routing. Experimental results are presented for typical interconnection schemes, and a prototype signal encoding/decoding network is demonstrated.
