Abstract

Abstract For improving the energy conversion efficiency from the pump to the available optical field in the microcavity, the dual coupled microcavities are proposed. Based on the coupled nonlinear Schrödinger equations, the optical field and spectrum characteristics inside the dual coupled microcavities can be studied, and the effect of the each parameter on the field is analyzed. Simulation results indicate that the bright soliton can exist in the coupled microcavities. The weak pump causes soliton breathers, even a sinusoidal field, while the increment of the pump power leads to the multi-pulse and chaos. Additionally, the trigger pulse has an important role to excite multi-pulse field and the mixed field. The diagram of the coupled field with various frequency detuning is also demonstrated. The significant soliton generates on the condition that the frequency of the first microcavity is in a certain range of several GHz. Theoretical analysis results are significant for studying the field in the dual coupled microcavities.
