我们表明，当边发射激光器中的纵向限制因子被视为动态变量时，调制传递函数有一个额外的项。当这些模式锁相足够长的时间（准锁相）时，该项在调制响应中产生一个补充的光子-光子共振峰，其频率对应于纵向模式之间的频率间隔。当两个连续的准锁相主纵向模式具有相似的纵向包络并且平均共享光子数量时，光子-光子共振峰最强。
We show that, when the longitudinal confinement factor in an edge-emitting laser is treated as a dynamic variable, the modulation transfer function has an extra term. This term produces a supplementary photon–photon resonance peak in the modulation response at a frequency corresponding to the frequency separation between longitudinal modes, when these modes are phase-locked long enough (quasi-phase-locked). The photon–photon resonance peak is strongest when two consecutive quasi-phase-locked dominant longitudinal modes have similar longitudinal envelopes and share equally the photon population.
