Soliton self-frequency shifts (SSFS) can be suppressed in optical fibers through spectral recoil, but this process leads to losses through continuous transfer of energy to a dispersive wave. We demonstrate a novel way to alter the strength of SSFS in photonic crystal fibers through a frequency-dependent nonlinear parameter $γ(ω)$. Our numerical simulations show both suppression and enhancement of SSFS depending on the sign of nonlinear slope. A large enough positive value of this slope can lead to total suppression of SSFS, without spectral recoil and without energy transfer to a resonant dispersive wave. Numerical simulations are supported by mathematical predictions based on the moment method.

Dual-laser self-injection locking to an integrated microresonator
半导体激光器自注入锁定高品质因数谐振腔回音壁模是一种广泛应用的激光线宽窄化和高频噪声抑制方法。SIL已经被用于超低噪声光子微波振荡器和孤子微梳产生的演示，并具有广泛的应用前景。到目前为止，SIL仅用单个激光器进行了演示。然而，多频和窄线宽激光源在现代电信系统、量子技术和微波光子学中有很高的需求。在这里，我们实验证明了两个多频激光二极管的双激光SIL集成硅$_3$ N $_4$微谐振器的不同模式。同时光谱崩溃的两个激光器，以及线宽变窄和高频噪声抑制，以及强的非线性相互作用的两个领域与对方，观察。将两个激光器锁定到相同的模式导致同时的频率和相位稳定以及它们的输出的相干相加。此外，我们提供了一个全面的双SIL理论，并研究了在微谐振器中的非线性效应所造成的激光对彼此的影响。
