Abstract

Photorefractive bidirectional ring oscillation was demonstrated experimentally some time ago [1]. Recently, a theory for the bidirectional oscillation in photorefractive ring resonators was proposed [2]. Interesting properties, such as intensity thresholding effect, may find applications in the fields of optical computing and optical neural networks [3]. Although, the steady stade oscillations are undstood, the stability of those oscillations has not been addressed. In this paper we present the linear stability analysis of photorefractive bidirectional ring oscillation under mean-field approximation and experimental confirmation of unstable oscillations.
