摘要： There is therefore provided in accordance with an embodiment of the present invention a modulator for modulating light comprising: a quantum well structure (QWS), comprising narrow-bandgap semiconductor layers interleaved with wide-bandgap semiconductor layers which QWS has an operating band of wavelengths for which transmittance for light is controllable by an electric field generated in the QWS; a configuration of electrodes electrifiable to generate an electric field perpendicular to the semiconductor layers of the QWS in each of a plurality of localized non-overlapping voxels of the QWS independent of an electric field in any of the other voxels; a different optical filter coupled to each of at least two of the voxels, each different filter transmitting light in a different sub-band of the operating band of the QWS and being substantially opaque to light having a wavelength in the operating band that is outside of the sub-band; and a power supply controllable to apply voltage to the configuration of electrodes so as to generate the electric field.
