Abstract

Since the observation of optical bistability, several papers have discussed the effect of a delayed feedback on instabilities pointing out that the transmited light from the system can be periodic or chaotic in time under certain conditions. This phenomenon was confirmed by Gibbs et al.¹ in hybrid bistable optical devices with PLZT as electrooptical material. Ukada et al.² have reported similar effects in LiNbO₃. In this case a coaxial line was employed as delay. A sustained oscillatory optical output is show to appear under the instable condition. Moreover, as we have shown previously,³ similar effects can be obtained from liquid crystal cells under suitable conditions, In this paper we extend these results giving an analytical model of some of the obtained oscillatory optical outputs.
