Abstract
Due to technological advances in the optical information processing and optical communication fields, the demands for higher performance in spatial light modulator. The anti-ferroelectric liquid crystal (AFLC) has a possibility of achieving multi-tone control by applied voltage similar to nematic LCD. The AFLC was developed as a new spatial light modulator, and furthermore, a high-speed drive method with polarization properties was proposed. From this, a high-speed drive of 500 μsec was confirmed. In addition, basic studies were conducted on necessary functions required for phase modulators, and phase modulation due to the effect of voltage control was verified. From these results, the feasibility for a high-speed multi-level spatial light modulator with the effect of AFLC was verified.
