Optical interconnection network.

摘要

An optical interconnection network comprises an optical bus (60) formed by a D-fibre (62) embedded in a thermoplastic substrate (64) with the flat of the D-fibre (62) flush with the top surface of the substrate. A module 70 similarly constructed is dimensioned to be a push fit in a wall structure formed on the substrate 64 with the fibres 72 and 62 in a position to evanescently couple optical signals from one fibre to the other.
