Paper Abstract

We present sensing characteristics of higher order rocking filters fabricated in highly birefringent microstructured fiber which resonantly couple polarization modes at several wavelengths. First rocking filter (RF1) shows tree resonances arising at 855, 1271, and 1623 nm, while in the second filter (RF2) the resonances arise at 908, 1145, 1354 and 1548 nm. We measured sensitivity to temperature in both filters and to hydrostatic pressure in the RF1. Our results show that both filters have very low response to temperature ranging from 1.38 to 3.03 pm/K depending on the resonance order. Simultaneously, the sensitivity to hydrostatic pressure is very high and reaches 6.14 and 3.30 nm/MPa, respectively for the first and the second resonance in the RF1. These unique sensitivity characteristics make the filters an excellent device for hydrostatic pressure measurement with no need for temperature compensation.
