Abstract

A technique is demonstrated for the accurate determination of differential propagation delays in fibre-optic circuits commonly found in sensing and signal processing arrays, utilising the high-order frequency filtering characteristics of these circuits. Relative time delays for two interferometers can be easily compared to within less than 10 ppm.
