Abstract
Fine tunability of oscillation frequency of optoelectronic oscillator (OEO) is crucial to its practicality. An approach of utilizing frequency locking technology is presented to realize the high-finesse tunable output of OEO based on SiO2 optical waveguide ring resonator (OWRR). Then the OEO system based on SiO2 OWRR is constructed, consisting of OEO loop and frequency locking loop. When the laser frequency is locked at the resonant frequency of the SiO2 OWRR, the stable single-mode oscillation is realized based on the filtering effect of SiO2 OWRR. The OEO oscillation frequency can be precisely tuned by adjusting the locking position of laser frequency, and a high-finesse tunable output of microwave signal is obtained with a tuning step of 20 kHz. Moreover, the change of locking position would not deteriorate the phase noise; for the generated signal at 2 GHz at different locking point, the phase noise is about -89.18 dBc/Hz at 10 kHz. These results show that the OEO based on SiO2 OWRR using frequency locking technology is feasible to obtain fine tunability of oscillation frequency. It indicates that the SiO2 OWRR has great potential in monolithic integrated OEO.
