Ultralow phase noise optoelectronic oscillator
Journal of Physics: Conference SeriesAbstract The optoelectronic oscillator(OEO)’s main technological advantage over the traditional microwave oscillator is its ultra-low phase noise property. In this article, we have been using a high-power low-RIN laser, a long fiber loop, and an ultra-low noise optical connection to generate an OEO with a phase noise of -162.5dBc/Hz ...
