Embodiment Construction
[0024] As shown in the figure is a schematic structural diagram of a tunable optoelectronic oscillator based on cross-phase modulation, including a 1550nm high-power narrow-linewidth laser 1, and the light waves output by the high-power narrow-linewidth laser are sequentially modulated by dual-drive electro-optical intensity device 2, optical coupler one 3, Mach-Zehnder interferometer and nonlinear fiber optic loop mirror, described Mach-Zehnder interferometer is made up of optical coupler two 4 and optical coupler three 5, and described nonlinear optical fiber The environment is composed of a wavelength division multiplexer 7, a highly nonlinear optical fiber 8, and an optical coupler 46. One end and two interfaces of the optical coupler 46 are respectively connected to the common end of the wavelength division multiplexer 7 and one end of the high nonlinear optical fiber 8. connected, the other end of the high nonlinear optical fiber 8 is connected to the input end of the wav...
