Abstract
The present disclosure provides a tunable broadband random optoelectronic oscillator, including: a laser light source configured to generate continuous laser light; a positive feedback loop formed by an intensity modulator, an optical circulator, an optical filter, an optical amplifier, a photodetector, an electric filter and an electric amplifier connected in sequence, wherein the positive feedback loop is configured to receive the continuous laser light to generate a microwave signal and achieve an optic-electro/electro-optic conversion; a Raman laser configured to generate Raman pump light; a wavelength division multiplexer having a first input terminal connected to the Raman laser and a second input terminal connected to the optical circulator; and a dispersion compensation fiber connected to an output terminal of the wavelength division multiplexer; wherein forward transmission laser light passing through the optical circulator and the Raman pump light are coupled into the dispersion compensation fiber through the wavelength division multiplexer.
