Abstract.  A theoretical analysis was conducted on the characteristics and performance of an optically combined dual-loop optoelectronic oscillator (OC-DOEO) based on an open-loop response method. The OC-DOEO utilizes the Vernier effect to eliminate spurious tones while accompanying the optical interference among the dual-loop signals. It was determined that the optical interference in the OC-DOEO significantly affected the OEO performances, including loop efficiency, phase noise, and spurious tones. It was demonstrated that DOEO performances can be maximized by controlling dual-loop parameters, such as the phase delay and power-split ratio, without spurious tones.
