Abstract:

With the rapid development of optoelectronic oscillators (OEOs), the methods of improving the phase noise of OEOs are becoming a new research topic. Based on explicating and analyzing their mechanism and characteristics, the techniques and schemes for decreasing OEOs’ phase noise are reviewed, and their principles and performance indexes are discussed. Finally, the factors restricting the phase noise and possible solutions are discussed.
