Abstract :
We have proposed a novel all-optical spatial light modulator based on complex refractive index changes upon photoexcitation of an organic dye-doped polymer thin film. In principle fs response can be achieved by this system, because we use resonance condition changes of the guided optical waves (guided mode) in the ATR geometry based on the changes in an imaginary or a real part of the refractive index due to transient absorption or its Kramers-Kronig transformation
