Abstract
This paper reports on our recent progress with lead-silicate suspended-core microstructured optical fibers (SC- MOFs) for the detection of liquids. Simulations for SC-MOFs with one micrometer core diameter and of two different glass compositions with refractive indices of 1.67 and 1.89 at 1550 nm are discussed. Mode-field area study is performed for liquid analytes within refractive index range of 1.65-1.75. Experimental results of evanescent-wave refractometry are presented, with an impact study of uneven analyte-filling impact on the sensor performance. Studied SC-MOFs can find their application as monitoring sensors of various liquid quality especially when spectroscopic approach is pursued.
