A compact fiber polarizer is demonstrated by the filling of selected air holes of a hollow-core photonic crystal fiber (PCF) with a liquid. The liquid-filling results in an asymmetric waveguide structure, leading to a large polarization dependent loss. A 6 mm long ethanol-filled PCF exhibits a polarization extinction ratio of ∼18 dB over a wavelength range from 1480 nm to 1600 nm.
一种紧凑型光纤偏振器通过将选定的空气孔填充到空心光子晶体光纤（PCF）中来实现。液体填充导致非对称波导结构，从而导致大的偏振相关损耗。在 1480nm 至 1600nm 的波长范围内，长度为 6mm 的填充乙醇的 PCF 表现出约 18dB 的偏振消光比。
