We present the first characterisation of cladding modes of a low-index contrast all-solid photonic bandgap fiber using an acousto-optic long-period grating. We experimentally measure the relative band diagrams of the cladding, visualise the fields of the cladding modes in the near field, and find both to be in good agreement with simulations. Our measurements and simulations show that the bands of the cladding are very sensitive to actual details of the structure.
我们展示了使用声光长周期光栅对低折射率对比度全固态光子带隙光纤包层模式的首次表征。我们通过实验测量了包层的相对能带图，可视化了近场中包层模式的场，并且发现两者与模拟结果吻合良好。我们的测量和模拟表明，包层的能带对结构的实际细节非常敏感。
