Abstract

Photorefractive mode coupling between resonators provides a simple model for self-pumped phase conjugators [1] where instabilities may occur due to energy transfer between different oscillation modes inside the crystal. In this paper, we consider the dynamical behaviors of mode coupling between two unidirectional ring resonators [2]. The first resonator is driven by an external laser beam via photorefractive two-wave mixing. The internal oscillating beam is then employed to drive the second ring resonator via the same mechanism (see Fig.1).
