“…It was already demonstrated in Ref. [7] that the scalar MI is sensitive to external parameters affecting the dispersion profile of the guided modes. This opens new possibilities for nonlinear sensing of several physical parameters by simultaneous interrogation of the scalar and vector MI bands.…”

“…The sensing principles utilized so far have typically been based on linear interaction of external physical/chemical parameters with guided light. Very recently an alternative approach has been proposed, combining the newest achievements in nonlinear optics driven by the emergence of a class of microstructured fibers with the development of fiber-optic sensing technology [5][6][7]. It is based on the direct sensitivity of nonlinear frequency conversion processes to variations in fiber dispersion.…”

Nonlinear frequency conversion in a birefringent microstructured fiber tuned by externally applied hydrostatic pressure

We studied vector frequency conversion in externally tuned microstructured fibers for applications as a novel, nonlinear fiber-optic sensor. We investigated both experimentally and numerically a possibility of shifting vector and scalar modulation instability gain bands by pressure-induced changes in the linear properties of a microstructured fiber. Our results show that polarization-dependent vector nonlinear processes sensitive to variation of fiber group velocity difference (group birefringence) exhibit a clear advantage for pressure-sensing applications compared with scalar nonlinear processes only sensitive to group velocity dispersion changes. Analytical predictions and numerical simulations confirm our measurement results.

“…The signal band shifts towards longer wavelengths at a rate of 2.8 nm/m, while the idler band shifts towards shorter wavelengths at a rate of 5.4 nm/ m. It is worth to note that the sensitivity to axial strain reported here is more than one order of magnitude larger than in a previous report [9] where a strain sensor based on four-wave mixing generated in a microstructured optical fiber pumped in the anomalous dispersion regime is demonstrated.…”

Effects of Temperature and Axial Strain on Four-Wave Mixing Parametric Frequencies in Microstructured Optical Fibers Pumped in the Normal Dispersion Regime

A study of the effect of temperature and axial strain on the parametric wavelengths produced by four-wave mixing in microstructured optical fibers is presented. Degenerate four-wave mixing was generated in the fibers by pumping at normal dispersion, near the zero-dispersion wavelength, causing the appearance of two widely-spaced four-wave mixing spectral bands. Temperature changes, and/or axial strain applied to the fiber, affects the dispersion characteristics of the fiber, which can result in the shift of the parametric wavelengths. We show that the increase of temperature causes the signal and idler wavelengths to shift linearly towards shorter and longer wavelengths, respectively. For the specific fiber of the experiment, the band shift at rates-0.04 nm/º C and 0.3 nm/º C, respectively. Strain causes the parametric bands to shift in the opposite way. The signal band shifted 2.8 nm/mand the idler 5.4 nm/mExperimental observations are backed by numerical simulations.

“…Also, it remains to be determined whether the unavoidable fluctuations in the microstructure along the PCF length after the activation of the fiber with the biolayers would decrease the effective FWM gain too much for the FWM peak to be detected [20], [21]. Since the theoretical prediction reported in [19], the nonlinear FWM-based sensing scheme has now experimentally demonstrated for refractive index [22], strain [23], and pressure sensing [24].…”

We demonstrate an experimentally feasible fiber design, which can act as a highly sensitive, label-free, and selective biosensor using the inherent high nonlinearity of an As 2 S 3 chalcogenide tapered fiber. The surface immobilization of the fiber with an antigen layer can provide the possibility to selectively capture antibody biomolecules. This increase of the layer thickness directly affects the group velocity dispersion of the fiber and, thus, the modulation instability (MI) gain spectrum changes (location of the anti-Stokes and Stokes wavelengths) when pumping the fiber close to the zero-dispersion wavelength. The sensitivity of the sensor was predicted to be ∼18 nm/nm, defined as the shift in resonance wavelength per nanometer biolayer thickness, which is almost twice the current record sensitivity of nonlinear MI-based fiber optical biosensors. Importantly, due to the strong nonlinearity of As 2 S 3 , this high sensitivity can be obtained using a low-power 1064-nm microchip laser.
