Integrated fourier domain mode-locked optoelectronic oscillator, application and communication system
An integrated Fourier domain mode-locked optoelectronic oscillator and its application and a communication system are provided, which relates to the technical field of microwave photonics. The integrated Fourier domain mode-locked optoelectronic oscillator includes an optoelectronic chip and an electronic chip. The optoelectronic chip includes a laser, a modulator, an optical notch filter, and a photodetector coupled via an optical waveguide. The electronic chip includes an electrical amplifier and a power splitter coupled via a coplanar microwave waveguide. The volume, weight and power consumption of the Fourier domain mode-locked optoelectronic oscillator is greatly reduced by integrating all the devices on the chip. A tunable sweeping microwave signal output is realized, and the sweeping speed of the output signal is increased. The integrated Fourier domain mode-locked optoelectronic oscillator can be used in radars and communication systems.
