“…Another important area of research within the field of plasmonic fiber-optic sensors can be developing new experimental setups for different fiber-optic designs. The use of novel light sources such as partially coherent beams [58], use of mid-infrared and THz regime light sources and detectors combined with plasmonic materials such as graphene [59,60], and finding cost effective ways to detect a change in intensity of light or location of absorption maxima can potentially transform the field.…”

Plasmonic fiber-optic biosensors combine the flexibility and compactness of optical fibers and high sensitivity of nanomaterials to their surrounding medium, to detect biological species such as cells, proteins, and DNA. Due to their small size, accuracy, low cost, and possibility of remote and distributed sensing, plasmonic fiber-optic biosensors are promising alternatives to traditional methods for biomolecule detection, and can result in significant advances in clinical diagnostics, drug discovery, food process control, disease, and environmental monitoring. In this review article, we overview the key plasmonic fiber-optic biosensing design concepts, including geometries based on conventional optical fibers like unclad, side-polished, tapered, and U-shaped fiber designs, and geometries based on specialty optical fibers, such as photonic crystal fibers and tilted fiber Bragg gratings. The review will be of benefit to both engineers in the field of optical fiber technology and scientists in the fields of biosensing.

“…In the past few years, a great deal of attention has been paid to partially coherent beams radiated by sources with non-Gaussian correlation functions [1][2][3][4][5][6][7][8][9]. This is due to a variety of extraordinary features that these beams exhibit on free-space propagation, such as self-splitting [10][11][12], self-focusing [13], self-steering [14], and useful shapes they acquire in the far field: flat-tops [15], rings [7,16], rectangles [17], grids [18], and dark-hollow intensity profiles [19]. These new properties have already stimulated new applications in optical particle trapping, free-space optical communications [20], classic imaging [21] and remote sensing [22].…”

Evolution of Spatiotemporal Intensity of Partially Coherent Pulsed Beams with Spatial Cosine-Gaussian and Temporal Laguerre–Gaussian Correlations in Still, Pure Water

et al. 2021

A new family of partially coherent pulsed beams with spatial cosine-Gaussian and temporal Laguerre–Gaussian correlations, named spatial cosine-Gaussian and temporal Laguerre–Gaussian correlated Schell-model (SCTLGSM) pulsed beams, is introduced. An analytic propagation formula is derived for the SCTLGSM pulsed beam through the spatiotemporal ABCD optical system characterizing a continuous dispersive medium. As an example, the evolution of spatiotemporal intensity of the SCTLGSM pulsed beam in a still, pure water column is then investigated. It is found that the SCTLGSM pulsed beams simultaneously exhibit spatiotemporal self-splitting and self-focusing phenomena, which can be attributed to the special spatial/temporal coherence structures and the presence of pulse chirper in the source plane. The physical interpretation of the obtained phenomena is given. The results obtained in this paper will be of interest in underwater optical technologies, e.g., directed energy and communications.

“…Nonetheless, recent advances in different fields require new source models with specific properties to be provided. In this sense, the control of the coherence properties of the source allows to obtain beams with peculiar behaviour of their intensity in propagation [8,[11][12][13][14][15][16][17][18][19][20][21][22][23].…”

Besinc Pseudo-Schell Model Sources with Circular Coherence

et al. 2019

Partially coherent sources with non-conventional coherence properties present unusual behaviors during propagation, which have potential application in fields like optical trapping and microscopy. Recently, partially coherent sources exhibiting circular coherence have been introduced and experimentally realized. Among them, the so-called pseudo Schell-model sources present coherence properties that depend only on the difference between the radial coordinates of two points. Here, the intensity and coherence properties of the fields radiated from pseudo Schell-model sources with a degree of coherence of the besinc type are analyzed in detail. A sharpening of the intensity profile is found for the propagated beam by appropriately selecting the coherence parameters. As a possible application, the trapping of different types of dielectric nanoparticles with this kind of beam is described.
