Numerical simulation of a D-type optical fiber sensor based on the Kretchmann's configuration and heterodyne interferometry

Phase‐sensitive surface plasmon resonance biosensors: methodology, instrumentation and applications

“…Experiments conducted on alcohol with variable concentrations showed a good agreement between simulations and experiment results [61]. Numerical simulations on 3-layer (glass core-goldsensing layer) [62] and 4-layer (glass core-silicon dioxidegold-sensing layer) [63] configurations of this D-type optical fiber sensor were carried out, and optimal parameters were suggested. Later, Chou et.…”

“…Optical heterodyning offers the third opportunity, which is based on the analysis of the differential frequency between two frequencyshifted orthogonally polarized s-and p-components of light reflected under SPR. Similarly to temporally modulated polarimetry, this approach makes possible an efficient noise removal and phase treatment tools [60][61][62][63][64][65][66], while its imaging prospects look more complicated. It is important that all three approaches are capable of providing much better sensitivities and related 1-2 order of magnitude lower detection limits.…”

“…Since 2005, Chiu and coworkers have reported a series of research works on the development of optical sensors based on the heterodyne detection [61][62][63]. Instead of using the prism coupler, their sensors were based on single mode optical fiber.…”

Non-contact method for measuring solution concentration using surface plasmon resonance apparatus and heterodyne interferometry

“…Their respective refractive indices are n 1 , n 2 = n + ik, and n 3 . The Fresnel reflection coefficients can be expressed as [11] r p ab ¼…”

Fiber optic SPR sensor for refractive index and temperature measurement based on MMF-FBG-MMF structure

“…Jorgenson for the first time [4], it has attained more and more attention. For instance, single-mode fibers are used in replacement of the traditional multimode fibers to enhance SPR sensor's sensitivity and narrow resonance peak [5][6]; fiber taper [7], side-polished D-shaped optical fiber [8], photonic crystal fiber [9] are used to improve the performance of the fiber optic SPR sensors.…”
