Abstract
The optoelectronic oscillator (OEO) is a time delayed system that exhibits a period doubling route to chaos. The period doubling nature of the OEO introduces bifurcation points where the system transitions from simple periodic behavior to chaotic dynamics. Near these bifurcation points, the OEO can amplify and mix weak injected radio-frequency signals. We introduce a simple model that effectively captures the dynamics of OEOs. Analytic expressions are derived and shown to agree with numerical simulations.
