Abstract Using a planar optical waveguide electro-optic modulator and simple double beam interfering device, the experimental study of optical bistability and multistability is succesfully performed. The waveguide modulator is made by depositing Aluminium as electrodes on the Ti-diffused LiNbO3 planar optical waveguide which is fabricated by ourselves. Laser beam is coupled directly into the end of optical waveguide modulator and out of the Bi12GeO20 prism. Optical rotation arising from Bi12GeO21 crystal is overcome in experiment. In addition to analyzing and discussing optical bistability the multistabilitical hysteresis curves of different shapes obtained in experiments are particularly investigated.
