A silica suspended-core microstructured optical fiber sensor for detection of liquids, operating at 1550 nm, is analyzed. The sensing principle is based on the evanescent wave overlap into a tested analyte, which is filled via capillary forces into the cladding holes. Validations for analytes in the refractive index range of 1.35-1.43 are carried out with(More)
The paper reports our progress on soft-glass fibers for optical switching purposes based on four-wave mixing. Specific development of connectorized nonlinear modules for switching application is presented. For the arsenic-selenide fiber we present a novel solid joint technology, with connection losses of only 0.25 dB, which is the lowest value presented(More)
We present theoretical and experimental results for a fiber optic refractometric sensor employing a semi-ellipsoidal sensing element made of polymethyl methacrylate. The double internal reflection of light inside the element provides sensitivity to the refractive index of the external analyte. We demonstrate that the developed sensor, operating at a(More)
Detecting explosive, flammable, or toxic industrial liquids reliably and accurately is a matter of civic responsibility that cannot be treated lightly. Tapered optical fibers (TOFs) and suspended core microstructured optical fibers (SC MOFs) were separately used as sensors of liquids without being compared to each other. We present a highly sensitive(More)
The age at which final nutria weight is achieved varies in literature between six and 14months. The aim of this study was to evaluate the growth, carcass composition and meat quality of male and female nutrias between the ages of six and eight months in intensive production system. Sexual dimorphism in growth was observed from three months of age, and in(More)
