Photonic integrated circuits (PIC) and photonic chips have the advantages of low power consumption, high speed, and large bandwidth, and they are the inevitable trend of the next generation optical information processing system. And on-chip light source is the key technology of PIC. An optical-pumping laser based on optical microring resonator is proposed, and the pumping light and laser light are output to different waveguides through the all-optical control. Combining the four-level two-electron energy level model and the time-domain finite difference method electromagnetic field simulation, the time-domain characteristics of laser output, particle state density and steady-state electromagnetic field mode distributions are analyzed. After 94 ps, the steady-state particle number density inversion distribution is reached, and pumping light of 1064 nm and laser light of 1550 nm are output to Through port of the upper channel and the Add port of the lower channel, respectively.
