Optical bistability, regenerative oscillation, and monostable pulse generation in a liquid crystal bistable optical device.
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.
Optical bistable device as electro‐optical multivibrator
A truly bistable device using an integrated optical cutoff modulator in LiNbO3 is reported. With appropriate optical input power, the device may be used as an electrical Schmitt trigger (electrical bistability). By electrical feedback, electro‐optical multivibrator operation is demonstrated.
