<p>In an organic/inorganic composite superlattice type optical modulator capable of entering/projecting light, and capable of modulating an optical characteristic such as transmittance, reflectivity, and a refractive index of light in response to an externally controlled electric field, or light, the organic/inorganic composite superlattice type optical modulator includes at least one sort of a compound semiconductor layer (1) and at least one sort of an organic compound layer (2); the compound semiconductor layer (1) and the organic compound layer (2) are alternately stacked in at least one period; at least one of the compound semiconductor layer (1) and the organic compound layer (2) owns crystalline; and also a thickness of each of the layers is made larger than a Bohr radius of the compound semiconductor, and 10 times smaller than it. As a result, this novel optical modulator can provide a high nonlinear characteristic by a semiconductor modulator, and a high response characteristic by an organic modulator. <IMAGE></p> |
