Abstract
Hybrid optical bistability and limiting using the DHS and SSFLC electro-optical effects in ferroelectric liquid crystal with linear feedback have been studied. Optical limiting and bistability are observed for the cases of negative and positive feedback parameters, respectively. It is also found that the hysteresis in the transmission-voltage curve of ferroelectric liquid crystal contributes to the expansion of the bistable region. Dynamic properties of switching between optical bistable states by the pulse incident light has also been studied.
