Solid state spatial light modulator

A spatial light modulator, comprising:

• an array of Faraday domains with each Faraday domain being selectively magnetizable to serve as an individual magnetic domain for selectively changing a polarization state of electromagnetic waves, having wavelengths that are no greater than a maximum wavelength, passing through each Faraday domain with each Faraday domain being characterized by physical dimensions and by a magnetization direction, that is settable to each one of a first direction and a second direction, for changing said polarization state and with each Faraday domain allowed to serve as said individual magnetic domain so long as the physical dimensions do not exceed a given maximum set of dimensions and said maximum wavelength corresponds to said given maximum set of dimensions;
• and
• an addressing arrangement for addressing the array of Faraday domains to selectively set the magnetization direction of each one of a group of adjacent ones of said Faraday domains to the same one of the first direction and the second direction such that the Faraday domains that make up the group of Faraday domains cooperate to change the polarization state of electromagnetic waves passing therethrough having wavelengths that are longer than said maximum wavelength.
