一个空气硅光子晶体光纤与金纳米线在核心中心示出支持低损耗的方位角偏振模式。由于所有其他模式都具有非常高的衰减，因此该光纤仅有效地支持这种模式，作为单偏振光纤，在宽波长范围内（在所报道的器件中为550-1650 nm）消光比>20 dB cm−1。它可以作为一种有效的方位模滤波器。
An air–silica photonic crystal fibre with a gold nanowire at core centre is shown to support a low-loss azimuthally polarized mode. Since all the other modes have very high attenuation, the fibre effectively supports only this mode, acting as a single-polarization fibre with an extinction ratio >20 dB cm−1 over a broad range of wavelengths (550–1650 nm in the device reported). It can be used as an effective azimuthal mode filter.
