A method for encoding information that is encoded in spatial variations of the intensity of light ( 24 ) of a first wave-length into light of a second wavelength, the method comprising: generating a first density distribution of electrons homologous with the spatial variations in intensity of the first wavelength light; generating a second additional electron density homologous with the first electron density distribution; trapping electrons from the first and second electron density distributions in a trapping region ( 34 ) to generate an electric field homologous with the density distributions in a material ( 36 ) that modulates a characteristic of light ( 22 ) that passes therethrough responsive to an electric field ( 46 ) therein; and transmitting the second wavelength light ( 22 ) through the modulating material ( 36 ) thereby modulating the second wavelength light in response to the electric field and encoding it with the information.
