Optoelectronic Oscillators Based on Fiber-Optic Resonators

Optoelectronic oscillators (OEOs) of a proposed type would be based partly on the use of fiber-optic linear or ring resonators in place of the long fiber-optic delay lines that have been used to obtain low phase noise in some previously developed OEOs. Although the proposal to use fiber-optic linear or ring resonators was made prior to the use of microsphere resonators described in the two preceding articles, this article appears as the third in the series because the two microsphere-related articles provide information that is prerequisite for appreciating the technical significance of the proposal.
