AI Technical Summary
Existing optoelectronic oscillators suffer from problems such as low frequency, small bandwidth, and high phase noise when generating arbitrary waveforms, and traditional solutions are difficult to achieve the stability of multimode oscillations and the diversity of signal types.
By employing an injection-locked optoelectronic oscillator and optical domain quadruple frequency technology, and utilizing a dual-polarization Mach-Zehnder modulator and an optical domain quadruple frequency device, the loop gain is controlled through injection locking and photoelectric conversion to generate high-frequency broadband arbitrary waveform signals.
It achieves the generation of arbitrary waveform signals with low phase noise and high stability, and can output continuous and pulse signals, with increased frequency bandwidth and significantly improved signal quality.
