“…Indeed, according to simulations, our metamaterial can deliver sensitivity of 400 nm/RIU (see the supplementary material), which is comparable to the state-of-the-art fiber based refractive index sensors. 14,[16][17][18]20,22,23,26,27,[44][45][46][47] Importantly, in our case, the large sensitivity of metamaterial to ambient refractive index is accompanied by very narrow line-width of the resonant dip (Dk 5 nm), leading to a high figure of merit (sensitivity/Dk) 20/RIU.…”

“…1. Compared to other reported methods of fiber nanostructuring, [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] this process results in a sample that contains only silica and silicon. Consequently, the metamaterial has very low loss in the near-infrared range and is tolerant both of high optical power as well as heating in general, due to strong adhesion between silica and silicon layers (and high melting point of both materials).…”

“…The possibility of reproducibly transferring suspended optomechanical structures is a unique feature of the employed transfer method, setting it apart from other methods involving e.g. transfer printing 41,42 , liquid-assisted transfer of patterned membranes 43 , and manual transfer with a micromanipulator tip [44][45][46][47] .…”

Nano-optomechanical sensors exploit light confinement at the nanoscale to enable very precise measurements of displacement, force, acceleration, and mass. Their application is hampered by the complex optical set-ups or packaging schemes required to couple light to and from the nano-optomechanical resonator. In this work, we present a fiber-coupled nano-optomechanical sensor that requires no coupling optics. This is achieved by directly placing a nano-optomechanical structure, a double membrane photonic crystal (DM-PhC), on the facet of a fiber, using a simple and scalable wafer-to-fiber transfer method. The device is probed in reflection and has a resonance at telecom wavelengths with a relatively broad spectral width of 3–10 nm, which is advantageous for a simple read-out and achieves a displacement imprecision of $$10\,{{\rm{fm}}}/{\sqrt{{\rm{Hz}}}}$$ 10 fm / Hz . Using resonant driving and a ringdown measurement, we can induce and monitor mechanical oscillations with an nm-scale amplitude via the fiber, which allows for tracking the mechanical resonant frequency and the mechanical linewidth with imprecisions of 79 and 12 Hz, respectively, at integration times of 4.5 s. We further demonstrate the application of this fiber-tip sensor to the measurement of pressure, using the effect of collisional damping on the mechanical linewidth, leading to the imprecision of $$9\times {10}^{-4}\,{\rm{mbar}}$$ 9 × 10 − 4 mbar with an integration time of 290 s. This combination of optomechanics and fiber-tip sensing may open the way to a new generation of fiber sensors with unprecedented functionality, ultrasmall footprint, and low-cost readout.

“…Similarly, in Ref. 162, measuring resonant wavelengths of different modes of a luminescent semiconductor photonic crystal cavity placed on the tip of an optical fiber are proposed and demonstrated for simultaneous measurement of RI and temperature. Lin et al 163,164 described an interesting, grating like, approach, where, instead, periodically, weak infiber mirrors are dispersed randomly along a short section of fiber (e.g., random grating) by application of femtosecond (Fig.…”

Multiparameter fiber-optic sensors: a review

2019

View full text Add to dashboard Cite

Needs for sensor miniaturization, versatile sensing solutions, and improved measurements' performances in difficult operating environments have recently driven considerable research in optical fiber sensor for multiparameter measurements. Multiparameter sensors not only enable new sensors' functionalities, but can also improve achievable measurement performances for some frequently measured parameters considerably. This study provides a review of work in the field of miniature fiber-optic sensors that allows independent and simultaneous measurements of two or more different physical or chemical parameters. Sensor designs and corresponding signal processing schemes are reviewed and compared.
