“…The effect of the hollow-core MOFs on to the emission wavelength and the amplitude of the fluorescent nanoparticles leads to the study of the potential applications of integration of the quantum dots into the hollow-core region [98,99]. Bozolan A. et al realized the temperature sensor based on MOF modified by the CdSe/ZnS nanocrystals through the measurements of their luminescence spectrum [41].…”

Microstructured optical fiber-based sensors (MOF) have been widely developed finding numerous applications in various fields of photonics, biotechnology, and medicine. High sensitivity to the refractive index variation, arising from the strong interaction between a guided mode and an analyte in the test, makes MOF-based sensors ideal candidates for chemical and biochemical analysis of solutions with small volume and low concentration. Here, we review the modern techniques used for the modification of the fiber’s structure, which leads to an enhanced detection sensitivity, as well as the surface functionalization processes used for selective adsorption of target molecules. Novel functionalized MOF-based devices possessing these unique properties, emphasize the potential applications for fiber optics in the field of modern biophotonics, such as remote sensing, thermography, refractometric measurements of biological liquids, detection of cancer proteins, and concentration analysis. In this work, we discuss the approaches used for the functionalization of MOFs, with a focus on potential applications of the produced structures.

“…The extraordinary characteristics of PCF like compact nature, robust, less environmental effects, lightweight, and minimum cost makes PCF based devices more popular which can easily work in enormous environmental conditions (Knight 2003). As compared to PCFs, conventional fibers have less structural flexibility due to which they have limitations in their versatile applications as in high power mechanism (Feehan and Price 2017), nonlinear fiber optics (Humbert et al 2006), spectroscopy (Holzwarth et al 2000), metrology, sensing applications (Prajapati 2019;Arif and Biddut 2017b), super-continuum generation (Zhao 2017), optical coherence tomography (Zhao 2017), quantum dots (Chibrova 2017)etc. PCF has many advantages over the traditional fiber e.g., high nonlinearity and negative dispersion with very low confinement loss (Frazao et al 2008;Pandey et al 2020;Pandey et al 2021), tuneable and high birefringence (Knight et al 1996), high effective area (Arif and Biddut 2017a), polarization-maintaining capability (Cordeiro et al 2006;Ayyanar 2017).…”

In this manuscript, we have designed a circular photonic crystal fiber (PCF) having three rectangular holes filled with GaP in the core region, three air hole rings and one annular air ring in the cladding region. We found highest negative dispersion for the 1.8 μm pitch along with very low confinement loss at wavelength 1.55 μm. This designed PCF offers high nonlinearity (39,612 W −1 km −1 ) and high negative dispersion (− 6586 ps nm −1 km −1 ) along with zero confinement loss at 1.55 μm wavelength. We also compared the proposed PCF with the previously published PCF structure and found that the nonlinearity and negative dispersion of the designed PCF are very high in comparison to circular air hole based PCF. Other performance parameters viz. birefringence, numerical aperture, effective area, and effective material loss are also analyzed.

“…In particular, this technique has been applied to cover glass, quarz and silicon substrates by composite multilayers containing polyelectrolytes and MNPs [10][11][12][13][14]. Also LbLA has been used to fill capillaries of HC-MFs with different materials, such as polymers [15] and metals [16], to reach specific functions [17][18][19][20][21][22].…”

Optical fibers are widely used in bioimaging systems as flexible endoscopes that are capable of low-invasive penetration inside hollow tissue cavities. Here, we report on the technique that allows magnetic resonance imaging (MRI) of hollow-core microstructured fibers (HC-MFs), which paves the way for combing MRI and optical bioimaging. Our approach is based on layer-by-layer assembly of oppositely charged polyelectrolytes and magnetite nanoparticles on the inner core surface of HC-MFs. Incorporation of magnetite nanoparticles into polyelectrolyte layers renders HC-MFs visible for MRI and induces the red-shift in their transmission spectra. Specifically, the transmission shifts up to 60 nm have been revealed for the several-layers composite coating, along with the high-quality contrast of HC-MFs in MRI scans. Our results shed light on marrying fiber-based endoscopy with MRI to open novel possibilities for minimally invasive clinical diagnostics and surgical procedures in vivo.
