We analyze the impact of pump depletion in the generation of parametrically driven Kerr cavity solitons in a degenerate optical parametric oscillator. Using variational methods, we derive an analytical expression that describes the soliton existence region. We use this expression to study the energy conversion efficiency and compare it to a linearly driven Kerr resonator modeled by the Lugiato-Lefever equation. Parametric driving is more efficient at high walk-off between the continuous wave driving and the soliton.
我们分析了在简并光学参量振荡器中,泵浦损耗对参量驱动 Kerr 腔孤子产生的影响。使用变分方法,我们推导出一个描述孤子存在区域的解析表达式。我们使用这个表达式来研究能量转换效率,并将其与由 Lugiato-Lefever 方程建模的线性驱动 Kerr 谐振器进行比较。在连续波驱动和孤子之间的走离较大时,参量驱动更为有效。
