Abstract

We firstly propose the simple technique to stabilize the output optical signal of the fiber ring resonator. The electronic feedback circuit, which consists of two voltage control oscillator (VCOs) and a low pass filter (LPF), is applied in fiber ring resonator to compensate the optical phase shift in the ring loop. The reference signal defines the operating condition of fiber ring resonator for desire optical signal output.
