Long period fiber gratings are fabricated in the cladding rods of all-solid photonic bandgap fibers (PBGFs) by point-by-point side UV illumination. Resonant couplings from fundamental mode to guided and radiative supermodes (rod modes), and bandgap-like modes are identified. We obtained a detailed insight over the modal and dispersive properties of the PBGF through a series of theoretical and experimental investigations on the spectral characteristics and the responses to temperature and high-index liquid of the LPGs.
通过逐点侧面紫外光照射，在全固态光子带隙光纤（PBGF）的包层棒中制备长周期光纤光栅。识别出从基模到导模和辐射超模（棒模）以及类似带隙模式的共振耦合。通过对长周期光栅的光谱特性以及对温度和高折射率液体的响应进行一系列理论和实验研究，我们对光子带隙光纤的模式和色散特性有了详细的了解。
