Abstract
We report on sensing characteristics of the rocking filter fabricated in specially designed microstructured fiber with enhanced sensitivity to hydrostatic pressure. The filter shows a very high sensitivity to pressure ranging from 16.2 to 32.2 nm/MPa, depending on the resonance order. Extremely low cross-sensitivity between pressure and temperature 27÷66×103 K/MPa has also been recorded and therefore the rocking filter can be used for pressure measurements with mbar resolution with no need for temperature compensation.
