Abstract

Two nonlinear RF photonic waveguides, one active and one lossy, are paired in a coupler setup. The stability of the configuration is investigated for various degrees of asymmetry between gain and loss, while the role of distance between the two components is examined. The enhancing influence of the gain saturation on system's stability and bistability is identified, while the basins of attraction for each fixed point are determined. The reported results unveil a wealth of dynamical features which are essential in various applications like non-reciprocal propagation, ultra-sensitive microwave sensing and tunable power teleportation.
