AI Technical Summary

Problems solved by technology

The microring resonator produced by this scheme has a right-angled optical waveguide inside, so it is difficult for light to pass through these right-angled optical waveguides, resulting in a large loss
In addition, when the laser irradiates the fiber optic fiber, it is difficult to precisely control the irradiation time, so that the refractive index of the irradiation position and the refractive index of the fiber core become exactly the same
