Description

technical field [0001] The invention belongs to the field of optoelectronic integration technology, in particular to an all-optical optical parametric oscillator. Background technique [0002] Optical parametric oscillation (OPO) is to convert the input wavelength to λ p The laser light (called pump light) is converted into two beams of signal light and idler light with unequal wavelengths through the second-order nonlinear optical effect, and the short wavelength is called signal light λ s , the long-wavelength idler light λ i , where the wavelength of the pump light is shorter than that of the signal light and idler light, such as figure 1 (a) shown. In the process of parametric oscillation, due to the dispersion effect of the nonlinear medium material, light waves of different frequencies have different propagation velocities and refractive indices when propagating in the medium, which leads to the generation of light waves with the same initial phase but different fre...
