A highly stable OEO using a multi-purpose optical-delay stabilization system

This paper presents the implementation of an active fiber optical-delay stabilization system in an optoelectronic oscillator. The primary use of the system is to stabilize optical point-to-point fiber links for synchronization purposes; however, the system can also be efficiently used as a stable optical delay line in an opto-electronic oscillator. By using a multipurpose optical delay stabilization system with an opto-electronic oscillator, a frequency drift of 0.02 ppm/K was achieved.
