Abstract

An optical device comprises an optical fibre device having wavelength-dependent optical characteristics mounted on a bimorph element operable to bend in response to an electrical control signal, so that the wavelength-dependent optical characteristics of the optical fibre device vary in response to bending of the bimorph element.
