It is known that dispersive fiber has an LP01 mode cutoff wavelength that acts as a wavelength filter. With a dispersive polysiloxane polymer overlay on a side-polished single-mode fiber, an in-line tunable fiber short-pass filter with a tuning range of approximately 400 nm (1250-1650 nm) and a temperature variation of 15 degrees C was demonstrated. The rejection efficiency was greater than 50 dB, whereas the insertion and polarization-dependent losses were below 0.26 and 0.09 dB, respectively.
已知色散光纤具有作为波长滤波器的LP01模截止波长。在侧面抛光的单模光纤上覆盖色散聚硅氧烷聚合物，展示了一种在线可调谐光纤短通滤波器，其调谐范围约为400纳米（1250 - 1650纳米），温度变化为15摄氏度。抑制效率大于50分贝，而插入损耗和偏振相关损耗分别低于0.26分贝和0.09分贝。
