“…The extreme surface sensitivity of the nanoporous film is due the large surface area as well as their ability to support various plasmonic modes. A prism-coupled SPR-based biosensor platform is commercially available and a Goos–Hänchen shift accuracy of 150 nm was recently achieved; therefore, these prototype silver–stibnite flexible nanoporous plasmonic films are a strong candidate for commercial biosensing applications.…”

The development of various plasmonic nanoporous materials has attracted much interest in different areas of research including bioengineering and biosensing because of their large surface area and versatile porous structure. Here, we introduce a novel technique for fabricating silver-stibnite nanoporous plasmonic films. Unlike conventional techniques that are usually used to fabricate nanoporous plasmonic films, we use a room-temperature growth method that is wet-chemistry free, which enables wafer-scale fabrication of nanoporous films on flexible substrates. We show the existence of propagating surface plasmon polaritons in nanoporous films and demonstrate the extreme bulk refractive index sensitivity of the films using the Goos-Hänchen shift interrogation scheme. In the proof-of-concept biosensing experiments, we functionalize the nanoporous films with biotin-thiol using a modified functionalization technique, to capture streptavidin. The fractal nature of the films increases the overlap between the local field and the immobilized biomolecules. The extreme sensitivity of the Goos-Hänchen shift allows femtomolar concentrations of streptavidin to be detected in real time, which is unprecedented using surface plasmons excited via the Kretschmann configuration.

“…We showed the increase of the Goos-Hänchen shift at the frequencies of the inside-photonic-band-gap modes and enhancement of the shift peaks due to the linear magneto-electric effect in the magnetic layers for the case of p-(s-) polarized transmitted beam produced by s-(p-) polarized incident beam. As shown in recent paper [64], modern experimental set-up allows provide a measurements with high accuracy for different polarization combinations even for relatively weak signal. We hope that the results of our analysis of Goos-Hänchen effect in bi-periodic photonic-magnonic crystals will be useful for the future investigation of complex multiperiodic photonic structures.…”

We present a theoretical investigation of Goos-Hänchen effect, i.e. the lateral shift of the light beam transmitted through one-dimensional bi-periodic multilayered photonic systems consisting of equidistant magnetic layers separated by finite size dielectric photonic crystals. We show that the increase of the number of periods in the photonicmagnonic structure leads to increase of the Goos-Hänchen shift in the vicinity of the frequencies of defect modes located inside the photonic band gaps. Presence of the linear magneto-electric coupling in the magnetic layers can result in a vanishing of the positive maxima of the cross-polarized contribution to the Goos-Hänchen shift.PACS number(s): 42.25. Gy, 42.25.Bs, 42.70.Qs I. INTRODUCTIONThe Goos-Hänchen effect consists in the lateral shift of a reflected light beam with respect to the prediction of geometric optics [1]. Nowadays, this effect is intensively studied [2][3][4][5][6][7] in different systems, including anisotropic crystals and magnetic materials [8][9][10][11][12][13][14][15][16], graphene [4,[17][18][19], superconductors [20,21], and photonic crystals (PCs) [19][20][21][22] despite the long history of investigations since the first observation of this phenomenon in 1947 [1]. Some aspects of Goos-Hänchen effect were studied in different structures (see for example recent review papers [23,24]). The Goos-Hänchen shift (GHS) of partially coherent light in epsilon-near-zero metamaterials was theoretically investigated in [25]. Giant GHS (up to 70 wavelenghts) and angular shift of several hundred microradians were observed in 2D metasurfaces composed of PMMA gratings on a gold surface [26]. Giant GHS has been predicted also for spin waves in magnetic films [27][28][29][30], and optical phonons [31]. This phenomenon has potential application in designing of integrated optics devices, such as optical switchers, bio-and chemical sensors and detectors [32][33][34][35][36].The GHS in multilayered systems can exhibit interesting peculiarities. For instance, giant GHSs are experimentally demonstrated from a prism-coupled PC structure through a bandgap-enhanced total internal reflection [37]. All-optical tunability of the GHS in PCs was demonstrated in [38]. The lateral shift of the reflected beam can be remarkably enhanced when the phase matching conditions are satisfied for the surface polaritons excitation at the interface of the structure in the graphene-induced photonic band gap (PBG) [39]. The GHS reversibility near the band-crossing structure of PCs containing lefthanded metamaterials was shown in [40]. The GHS at the PBG edges can reach values up to several hundreds of wavelengths [41]. Similarly, when a light beam is incident on a PC containing a defect layer, the GHSs are greatly enhanced near the defect mode due to the electromagnetic waves localization [42].On the contrary, in PT-symmetric crystals the GHS can be huge inside the reflection band [43,44]. The following bi-periodic structures are also of potential interest: photonic-magnonic crystals (PMCs) w...

“…A QD is a position sensor based on a photoelectric effect. Due to its advantages of being high resolution, fast response, and low cost [1][2][3], it has become a popular non-contact measurement instrument. Therefore, it is widely used in laser guidance [4], laser tracking [5], sub-nanometer measurements [6], space laser communication [7], and synchronous optical position detection [8], as well as in other fields.…”

In atmospheric laser communication, a beam is transmitted through an atmospheric channel, and the photocurrent output from a quadrant detector (QD) used as the tracking sensor fluctuates significantly. To ensure uninterrupted communication and to adapt to such fluctuations, in this paper we apply logarithmic amplifiers to process the output signals of a QD. To further improve the measurement accuracy of the spot position, we firstly propose an integral infinite log-ratio algorithm (IILRA) and an integral infinity log-ratio algorithm based on the signal-to-noise ratio (BSNR-IILRA) through analysis of the factors influencing the measurement error considering the signal-to-noise ratio (SNR) parameter. Secondly, the measurement error of the two algorithms under different SNRs and their variations are analyzed. Finally, a spot position detection experiment platform is built to correctly and efficiently verify the two algorithms. The experimental results show that when the SNR is 54.10 dB, the maximum error and root mean square error of the spot position of the IILRA are 0.0054 mm and 0.0039 mm, respectively, which are less than half those of the center approximation algorithm (CAA). When the SNR is 23.88 dB, the maximum error and root mean square error of the spot position of the BSNR-IILRA are 0.0046 mm and 0.0034 mm, respectively, which are one-thirtieth and one-twentieth of the CAA, respectively. The spot position measurement accuracy of the two proposed algorithms is significantly improved compared with the CAA.
