Abstract

A hybrid bistable optical device is realized by using a simple liquid crystal light modulator based on the dynamic scattering. Its low driving voltage and high transmission for the ON state make the amplification of feedback signal unnecessary and may facilitate a 2-D spatial array of devices. Regenerative oscillation and monostable pulse generation have also been demonstrated to study its transient behavior.
