Using a planar optical waveguide electro-optic modulator and simple double beam interferingdevice,the experimental study of optical bistability and multistability is successfully performed.Thewaveguide modulator is made by depositing aluminium as electrodes on the Ti-diffused LiNbO_3planar optical waveguide which is fabricated by ourselves.Laser beam is coupled directly into theend of optical waveguide modulator and out of the Bi_(12)GeO_(20)prism.Optical rotation arising fromBi_(12)GeO_(20)crystal is overcome in experiment.In addition to analyzing and discussing optical bi-stability,the multistabilitical hysteresis curves of different shapes obtained in experiments are particu-lariy investigated.
