Abstract

The input pump light field can be split into two transverse modes, after entering a AIN microring, which can generate rich nonlinear effects. The cross-phase modulation (XPM) effect in magnetic(TM) polarization mode can cause a refractive index alteration of the micro-ring, the electric(TE) polarization mode and TM polarization mode will display different values and generate a phase change. By adjusting the magnitude of the input TE polarization mode and TM polarization mode, we can achieve a series of phase distributions. By controlling the phase of the electromagnetic field, we can control orbital angular momentum (OAM). The traditional LLE does not take phase into account, in this paper, we obtain a generalized LLE includes phase case. Our research suitable for precision spectroscopy, optical communication links, and coherent information processing.
