Abstract

A simple method of quadrature control for an interferometer is described in which a thermal fibre modulator is provided by a fibre coated with a metal jacket which can be vacuum evaporated or simply painted on, either to the bare fibre or to the jacket. The electronic feedback control is provided by a single power amplifier chip.
