We demonstrate that higher order rocking filters coupling energy between polarization modes at several wavelengths can be fabricated in a birefringent photonic crystal fiber using a fusion arc splicer. Three resonant couplings were identified, respectively at 855, 1271, and 1623 nm for the filter with a pitch distance of 8 mm characterized in this work. We also measured the filter response to temperature, elongation and hydrostatic pressure at the first and the second resonance. Our results show that the fabricated filter has very low sensitivity to temperature 1.77 and 1.38 pm/K, moderate sensitivity to elongation 1.35 and 1.12 nm/mstrain, and extremely high sensitivity to hydrostatic pressure 6.14 and 3.30 nm/MPa, respectively at the first and the second resonance.
我们证明，使用熔接机可以在双折射光子晶体光纤中制造出能够在多个波长下在偏振模式之间耦合能量的高阶摇摆滤波器。对于在本工作中表征的节距为8毫米的滤波器，分别在855、1271和1623纳米处识别出三种共振耦合。我们还测量了该滤波器在第一和第二共振处对温度、拉伸和静水压力的响应。我们的结果表明，所制造的滤波器在第一和第二共振处分别对温度具有非常低的灵敏度，为1.77和1.38皮米/开尔文，对拉伸具有中等灵敏度，为1.35和1.12纳米/微应变，对静水压力具有极高的灵敏度，为6.14和3.30纳米/兆帕。
