Abstract

We investigated a particular design of a highly birefringent PCF with attractive features for pressure sensing applications. A plane-wave method together with the finite element method were used to numerically calculate phase and group modal birefringence, pressure and temperature sensitivities of our fiber. The simulation results together with the experiments demonstrate a considerable difference between a very high phase birefringence (B ∼ 10−3) and a very low negative group birefringence (G −10−3). Our fiber exhibits a low and positive temperature sensitivity (KT < 0.1 rad/(K⋅m)), and relatively high and negative mechanical (pressure) sensitivity (Kp ≤ −10 rad/(MPa⋅m)), which supports its possible use as a mechanical sensor that does not require any temperature compensation.
