Claim 16:
17. A spatial light modulator, comprising:
a resonant surface to reflect incident signal light at a resonant wavelength; and
at least one incoherent light source, in optical communication with the resonant surface, to tune the resonant wavelength of at least one oscillator of the resonant surface by at least 20% of a linewidth of the at least one oscillator via optical free carrier injection and to modulate amplitude and phase of signal light incident on the at least one oscillator, wherein the at least one oscillator comprises a photonic crystal cavity or a cavity region containing at least one semiconductor layer, a first distributed Bragg reflector (DBR) disposed at a first end of the cavity region, and a second DBR disposed at a second end of the cavity region to form a resonant cavity.
