Abstract:
1. A method, comprising: providing an opto-electronic oscillator device having a closed opto-electronic loop which comprises an electronic section and an optical section and forms a positive feedback loop, wherein the closed opto-electronic loop includes an input port to receive an input signal at an input signal frequency and an output port to output an output signal at an output signal frequency; setting the closed opto-electronic loop at an initial state with a loop gain below an oscillation threshold when the input port does not receives the input signal; injecting the input signal into the input port to operate the closed opto-electronic loop above the oscillation threshold to produce and sustain an oscillation signal in the closed opto-electronic loop; and coupling a portion of the oscillation signal out of the closed opto-electronic loop to produce the output signal at the output port.
