Abstract
A modulator assembly for modulation of light, for use as part of an opto-electronic communication network, has a light modulator assembly comprising a modulator element comprising a modulating medium for modulating the intensity of light passing therethrough. A single electrode applies an electric field across the modulating medium and heats the medium. The medium has an absorption edge at a wavelength dependent on the temperature of the medium and the applied electric field. The electrode heats the modulating medium such that the wavelength of the absorption edge aligns with the wavelength of the light to be modulated.
