Surface plasmon resonance based tapered fiber optic sensor with different taper profiles

Current status of micro- and nano-structured optical fiber sensors

“…6 and Table 2. These include symmetrical structures, such as a simple metal coated optical fiber with and without remaining cladding [22][23][24][25][26][27], tapered fiber [28][29][30], structures without any symmetry, such as side-polished fibers (or D-shape fiber) and one-side metal coated fibers with and without remaining cladding [31][32][33][34][35][36][37][38], and structures with modified fiber tips with flat or angled structures [10,[39][40][41][42]. Each of them may contain either overlayer or multilayer structures.…”

“…In designing the sensor head, the tapering ratio and the diameter of the uniform region need to be considered [28,44]. When one designs a reflection type of SPR fiber sensor with a metal-coated fiber tip, the angle and the shape of the tips should also be considered [10,41,57].…”

The Sensing Characteristics of a Bragg Fiber Based Plasmonic Biosensor Using an As<sub>2</sub>S<sub>3</sub> Chalcogenide Layer

“…In the following simulations the refractive index of silica [9][10][11], distilled water [12] and As 2 S 3 [13] materials are calculated through a Sellmeier relation, whereas that of the gold layer is determined with a Drude formula [9][10]14]. …”

Surface plasmon resonance based fiber optic sensor for the detection of triacylglycerides using gel entrapment technique

“…More recently, the use of the surface plasmon resonance technique in optical fiber configuration has emerged as a comparatively simple, rapid, sensitive and is not affected by electromagnetic interference [8][9][10][11][12][13][14]. In fiber optic SPR sensors a small unclad portion of the optical fiber is coated with metal layer and the dielectric to be analyzed is around this metallic layer.…”
