Abstract

A simple thin film thickness monitor involving optical fibre components is described. The film was deposited onto the cleaved end of an optical fibre using vacuum techniques. The thickness was determined by monitoring the return power via a 2x2 directional coupler arrangement. This optical monitor was used to calibrate a conventional quartz crystal monitor.
