T. Oyama et al., TRISTABLE OPERATION OF ANTIFERROELECTRIC LIQUID-CRYSTAL LIGHT VALVES OPTICALLY ADDRESSED USING AMORPHOUS-SILICON PHOTOSENSOR, JPN J A P 2, 32(5A), 1993, pp. 668-670
Antiferroelectric liquid crystal has recently been developed, which ha
s three stable states and shows three levels of transmittance against
the polarity of field. In this study, we have fabricated antiferroelec
tric liquid crystal light valves with tristable operation using the re
sistance change of amorphous silicon which is dependent on the intensi
ty of input light. We have realized control of the intensity of output
light at three different values as a function of intensity of input l
ight.
