“…In this study, we have further developed a simple technique of employing an electronic feedback circuit to stabilize the optical output signal of the fiber ring resonator [23]. Although the concept is similar to previous works [15]- [17], the principle of circuit operation is different, and the stabilization is improved.…”

We propose a simple technique to stabilize the optical output intensity of a fiber ring resonator. The electronic feedback circuit system, which consists of two voltage control oscillators, a phase comparator, and a low pass filter, is applied to the fiber ring resonator in order to compensate the optical phase shift in the ring loop. The reference electrical signal determines the operating condition of the fiber ring resonator for the desired optical output signal. The experimental results within the operating range agree well with the analytical results. The simulated performance of the proposed model is also compared with that of other existing models and shows significant improvement over them.
