Summary form only given. We report on the fabrication and performance characterization of the first pixelated infrared-sensitive optically addressed spatial light modulator (OASLM) made of nematic liquid crystal (NLC) and InGaAs p-i-n photosensor array. We fabricated a low dark-current, high-responsivity InGaAs p-i-n photodiode array with a broad spectral responsivity. The 2-/spl mu/m thick InGaAs p-i-n photodiode was grown by molecular beam epitaxy on an InP substrate.
