论文摘要
我们研究了固体核心PCF中的联运前向brirouin散射，表明HE11和HE21模式之间有效的功率转化，最大增益系数为21.4/w/km。通过探索不同对称性的机械模式，我们观察到偏振依赖性和独立于极化的地间布里鲁因相互作用。最后，我们讨论了挤压膜空气阻尼和泄漏机制的作用，最终对于PCF结构的工程至关重要，并通过弯曲机械模式在高阶光学模式之间增强了相互作用。
We investigate intermodal forward Brillouin scattering in a solid-core PCF, demonstrating efficient power conversion between the HE11 and HE21 modes, with a maximum gain coefficient of 21.4/W/km. By exploring mechanical modes of different symmetries, we observe both polarization-dependent and polarization-independent intermodal Brillouin interaction. Finally, we discuss the role of squeeze film air damping and leakage mechanisms, ultimately critical to the engineering of PCF structures with enhanced interaction between high order optical modes through flexural mechanical modes.
