Optical Fiber-Top Microcavity Sensor for CO2 Detection

Wu J., Yin M-J, Taeuber K., Dani A., Guterman R., Yuan J., Zhang A.P., Tam H-Y, The Hong Kong Polytechnic University, HK

In the paper, we present a miniature fiber-optic CO2 sensor by in-situ printing of a special polymer Fabry-Pérot (FP) microcavity on the end facet of standard single-mode optical fiber. A photo-crosslinkable poly(ionic liquid)s (PILs) with [...]

Fiber-optic sensor for bacteria detection based on intensity-modulated SPR by monochromatic excitation

da Silva Arcas A., da Silva Dutra F., da Silva Arcas A., da Silva Dutra F., Barros Allil R.C.S., Werneck M.M., Federal University of Rio de Janeiro, BR

The Escherichia coli (E. coli) O157:H7 is a human pathogen of animal origin that can cause serious illness if ingested. The most common routes of E. coli contamination are drinking water, vegetables, undercooked meat, unpasteurized [...]

Photonic Crystal Fiber Based Refractive Index Sensor

Nazeri K., Ahsani V., Ahmed F., Lee P-C, Jun M.B.G., Purdue University, US

Photonic Crystal Fiber (PCF) is an optical fiber which owes its waveguide properties to an arbitrary arrangement of closely-spaced and tiny air holes that go through the whole length of fiber. Much attention has been [...]

Fiber Optic Sensors for High Temperature Monitoring

Rinaudo P., Torres Górriz B., Barrera Villar D., Sales Maicas S., Calderón García P.A., Javier Payá-Zaforteza I., Universitat Politècnica de València (Spain), ES

Recent events such as the fires on the Channel tunnel (1996), St. Gotthard (2001), the Twin Towers in New York (2001), The Windsor Building in Madrid (2005) and the collapse of the MacArthur Maze in [...]

Fiber Optic Based Evanescent Wave Sensor for the Detection of Elemental Mercury Utilizing Gold Nanorods

Crosby J.S., Lucas D., Koshland C.P., University of California-Berkeley, US

We have developed a fiber optic based sensor for the detection of atmospheric elemental mercury that uses gold nanoparticles as the sensing medium. Previous work has established that the Localized Surface Plasmon Resonance Peak blue-shifts [...]
