An optically powered optical modulator comprises an optical modulation component, such as an electro-optical modulator, acousto-optic modulator or magneto-optic modulator, in combination with one or two lens assemblies positioned at one or both apertures of the optical modulation component, so that the optical modulator formed by the combination of the lens assembly or assemblies and the optical modulation component has optical focus power.
