“…At the same time, there is a series of known published works [59][60][61][62][63][64][65][66][67][68][69][70][71][72] , which suppose and further confirm, based on performed both simulations and experimental researches, that induced twisting over MOFs and PCFs with specified configuration also adds new unique waveguide features. These spun, helical or twisted MOFs are declared as alternative mode converters 59 , special optical fibers for polarization maintenance and generation of optical activity [60][61][62][63] , and new kind of fiber optic electric current / magnetic field sensors 64 or twisting / strain sensors [65][66][67] as well as they are considered as new type of optical fibers with great potentiality for guiding and transmission of orbital angular momentum (OAM) modes [68][69][70][71] . Therefore, we supposed, that combination of two basic complicated fiber optic structuresmulti-core MOFs and twisted MOFswill add novel unique properties to this new type of optical fibers.…”

“…Gold is the most appropriate plasmonic material. Since it has high biocompatibility with less oxidation in an aqueous and humid environment (Mollah et al 2019 ) and also compromises high resonance shift and chemical stability. In the proposed SPR sensor we have used gold as a plasmonic material due to its efficient characteristics.…”

For the quick detection of the new Coronavirus (COVID-19), a highly sensitive D-shaped gold-coated surface Plasmon resonance (SPR) biosensor is presented. The COVID-19 virus may be quickly and accurately identified using the SPR-based biosensor, which is essential for halting the spread of this excruciating epidemic. The suggested biosensor is used for detection of the IBV i.e. infectious bronchitis viruses contaminated cell that belongs to the family of COVID-19 having a refractive index of − 0.96, − 0.97, − 0.98, − 0.99, − 1 that is observed with the change in EID concentration. Some important optical parameter variations are examined in the investigation process. Multiphysics version 5.3 with the Finite element method is used for the proposed biosensor. The proposed sensor depicts maximum wavelength sensitivity of 40,141.76 nm/RIU. Some other parameters such as confinement loss, crosstalk, and insertion loss are also analyzed for the proposed sensor. The reported minimum insertion loss for the refractive index (RI) − 1 is 2.9 dB. Simple design, good sensitivity, and lower value of losses make the proposed sensor proficient for the detection of infectious bronchitis viruses belonging to COVID-19. Graphical abstract

“…7 GeO2doped hollow ring cores (7-GeO2-doped HRCs)), and induced twisting, including orders 130 and 300 revolutions per meter (rpm). Primary motivation of implementing described above twisted multi-HRC MOF was attempt to combine following basic fiber optic structures: multi-HRC optical fiber 1,2 , complicated by with MOF 3,4 , which combination is considered as one of the most promising configurations for based on orbital angular momentum (AOM) spatial/mode division multiplexing (SDM/MDM) technique for optical networks 5 , and twisted MOF, that are also declared as alternative solutions for fiber optic sensors 6,7 (both for twisting/strain 6 and electric current/magnetic field 7 detection and estimation) and alternative fiber optic guiding systems for transmission of OAM modes 8,9 . Therefore, we suppose, that twisted multi-HRC MOFs can be considered as new complicated fiber optic element with unique features and potentiality for applications in both eigen and OAM mode management devices for applications in optical networks and fiber optic sensors.…”

This work introduces first time fabricated spun silica microstructured optical fiber (MOF) with inclusion seven GeO2-doped capillaries, placed in the central part of MOF cross-section, and induced twisting. While Part I discussed technological issues for manufacturing of described complicated twisted fiber optic structure, presented some pilot samples of described MOFs with various twisting order and measured their transmission spectra, Part II describes some results of results of experimental researches, performed for successfully manufactured twisted MOF pilot samples with typical hexagonal geometry under hole radius 4.40 μm and pitch 9.80 μm, outer “telecommunication” diameter 125 μm, and center part, formed by seven hollow GeO2-doped ring cores with inner radius 2.50 μm, pitch 8.80 μm and refractive index difference Δn=0.030 with induced twisting 130, 300 and 730 revolutions per meter. Following test series were performed: measurements of far-field laser beam profiles, some attempts of fusion splicing of typical telecommunication optical fibers and fabricated MOF with insertion loss estimation, and spectral response measurements of both single and group WDM (Wavelength Division Multiplexing)-channels of commercially available telecom WDM-system under inclusion of 2 m length MOF into various spans of short-range lab fiber optic link.
