Embodiment Construction
[0027] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] figure 1It is a structural schematic diagram of the photoelectric oscillator based on the multilayer film optical microcavity proposed by the present invention. The optoelectronic oscillator consists of a laser 1, a polarization controller 2, a Mach-Zehnder intensity modulator 3, an RF amplifier 4, a high-speed photodetector 5, a SNAP microcavity 6 and a laser frequency locking module 8 to form a closed optoelectronic feedback loop. The road is the main structure of the photoelectric oscillator; wherein, the laser 1 is connected to the input end of the Mach-Zehnder intensity modulator 3 after passing through the polarization controller 2, and is used to generate a comb spectrum, and the polarization controller controls the polarization state of the input light, and the Mach-Zehnder intensity modulator 3 The Zender intensity m...
