Abstract
Side-hole fibers are one of the most hopeful types of fibers applied in pressure measurements. They have high sensitivity to pressure due to the presence of two air channels placed symmetrically near the circular or cylindrical core. In this paper, results of research of side-hole fibers with elliptical core are presented. The beat lengths of these fibers as well as the pressure and temperature sensibility were measured. The pressure sensibility reached 150 rad/MPa(DOT)m for the most sensitive fiber; that is a value 15 times greater than the sensitivity of standard birefringent fibers. Relation between the pressure and temperature sensitivity seems to be hopeful also, because their quotient was about 100 K/MPa for most of examined fibers.
