摘要： A non-volatile programmable electro-optical element alters absorption characteristics of an optical medium that comprises a doped transition metal oxide material including F-centers. The F-centers are electrostatically moved into or out of the regions containing a wavefunction of an optical beam. A specific F-center profile in the transition metal oxide material may be programmed into the optical medium. The F-center profile alters an absorption profile within the optical medium. The spectral range for transmission of electromagnetic radiation in the optical medium may be tailored by the F-centers. Once the absorption profile is set by an electrical signal, the optical element maintains its state even when the electrical signal is turned off. Thus, the programming node may be disconnected from a power supply network, thereby enabling a low power operation of the electro-optical element. The inventive electro-optical element may be employed for both the visible and the infrared wavelength spectrum.
