  • 不同的频率失谐会在耦合光学微腔激发出不同的工作模式. 以两个耦合光场的非线性薛定谔方程为理论模型, 分别研究了失谐参量正调谐和负调谐过程中微腔内光场的变化. 理论分析结果表明, 在正失谐区域中, 腔内光场可由多脉冲形式演变为亮孤子, 但亮孤子存在范围较小, 当失谐参量过大时, 腔内光场会演化为直流分布. 在负失谐区域, 腔内可以形成较高功率“图灵环”形式的光场. 当耦合微腔没有发生频率失谐, 或者失谐参量接近0时, 腔内只能形成混沌形式的光场分布. 当耦合微腔内激发出光孤子后, 通过选取合适的失谐参量和抽运功率, 可在腔内维持稳定的亮孤子. 此外还可通过继续调谐第一个微腔的失谐参量, 将亮孤子转变为低功率的“图灵环”. 理论分析结果对耦合微腔的实验研究具有重要意义.
    Different frequency detuning can excite different working mode in a dual coupled optical microcavities. Based on the nonlinear Schrödinger equations of dual coupled field, and by using the split-step Fourier method, the optical field evolution in the microcavities is analyzed under the condition of both positive and negative tuning, and various optical distributions are generated in the process of frequency tuning. Simulation results indicate that the field can develop into the bright soliton in the region of positive tuning. However, the region in which the bright soliton is maintained is small, and the field in the microcavities grows into direct current (DC) distribution because of the serious frequency detuning. In the region of negative tuning, the field of “turning pattern” with high power is generated. There is only chaos inside the microcavities without frequency detuning or the detuning parameters close to 0. In addition, under the condition of strong coupling, the bright soliton and the “turning pattern” cannot be excited. Even stronger coupling leads to optical field in the form of DC directly. After the bright soliton exciting in the microcavity, it can be preserved by selecting appropriate detuning parameters and pump power. Moreover, the bright soliton can be changed into “turning pattern” with low power by continuously changing the detuning parameter of the first microcavity. Theoretical analyses are significant for experimental research on the dual coupled microcavities.
