High temperature tolerant optical fiber inline microsensors by laser fabrication
"Fiber sensors are particularly attractive for harsh environment defined by high temperature, high pressure, corrosive/erosive, and strong electromagnetic interference, where conventional electronic sensors do not have a chance to survive. However, the key issue has been the robustness of the …

Numerical Analysis of Optically-induced Long-period Fiber Gratings for Sensing Applications
Long-period fiber gratings (LPGs) with a period ranging from several hundred micrometers to a few millimeters can couple a core mode to discrete co-propagating cladding modes when the phase matching condition is satisfied. The rapid attenuation of cladding modes results in loss bands in the …

Ionic Self-Assembled Multilayers in a Long Period Grating Sensor for Bacteria and as a Source of Second-Harmonic Generation Plasmonically Enhanced by Silver Nanoprisms
… to tune and functionalize a rapid, sensitive fiber optic biosensor for textit{Brucella}, a family of bacteria that are detrimental to livestock and can also infect humans. The sensor was based on a turn-around point long period fiber grating (TAP-LPG). Unlike conventional LPGs, in which the …

Sensitivity control of optical fiber biosensors utilizing turnaround point long period gratings with self-assembled polymer coatings
… Self-Assembled Multilayers (ISAMs) adsorbed on Long Period Gratings (LPGs) can serve as a highly sensitive, robust, inexpensive optical-based biosensor platform. The ISAM technique is a layer-by-layer deposition method that builds nanometer-thick films based on the principle of Coulomb …
