The light radiated from the guided mode of a hollow core photonic crystal fiber into free space is measured as a function of angle and wavelength. This enables the direct experimental visualization of the photonic band gap and the identification of localized modes of the core region.
从空心光子晶体光纤的导模辐射到自由空间的光，被测量作为角度和波长的函数。这使得光子带隙的直接实验可视化以及核心区域局部模式的识别成为可能。
