摘要：

A novel forced oscillation technique is discussed for the phase noise reduction of electrical and optoelectronic oscillators. This paper features self-injection locking using single and dual long fiber-optic delay loops and provides analysis for the phase noise of oscillators employing this technique under various operating conditions. Experimental results are also provided to verify the analytical modeling and to identify techniques to further enhance spectral purity of oscillators.
