“…Since then, more and more 2D materials comed into people's view. Different from the threedimensional materials, the restriction of electrons in two dimensionalities brings huge changes of 2D materials in physical and chemical properties [3][4][5][6] and made great breakthroughs and innovations in the fields of optics, mechanics, energy storage, sensing, catalysis, and so on [7][8][9][10][11][12][13]. At the same time, the researches in the nonlinear optics of 2D nanomaterials have been boosting like the mushrooms after spring rains.…”

Selenium (Se) is located in the fourth period of the periodic table in group VIA (element 34). In this experiment, three different solvents (isopropyl alcohol, N-methyl-2-pyrrolidone, and ethanol) were used to prepare the two-dimensional (2D) Se nanosheets, which were manufactured by the liquid phase exfoliation (LPE) method with a thickness of 3.35 ~ 4.64 nm and a transverse scale of several hundred nanometers. The nonlinear absorption (NLA) properties at 355, 532, and 1064 nm were studied using the open aperture Z-scan technique. Final results showed that Se nanosheets exhibited optical limiting (OL) effect in all three wavebands and three solvents, and had large two-photon absorption coefficients, especially in ultraviolet (UV) waveband. Which proved that Se nanosheets had great potential application as excellent OL materials in UV waveband. Our research broadens the path for the semiconductor field of Se, inspires the application of Se in nonlinear optics field.

“…This requires specific substances to be sputtered onto the optical fiber cladding surface, for example, lutetium bisphthalocyanines for nitrogen dioxide measurement [35], a gold layer for bacterial density monitoring [36], graphene oxide for relative humidity measurement [37], polyvinyl alcohol for relative humidity sensing [38], graphene oxide and staphylococcal protein A for human IgG detection [39], magnetic fluid for magnetic field measurements [40], Au nanoparticles for mercury ion detection [41], and indium tin oxide for vector twist measurement [42]. Refractometers using TFBGs are also a separate group [43][44][45][46]. However, all proposed RI change sensors using TFBGs are inherently sensitive to changes in the state of the input light polarization plane.…”

This article proposes a new method for detecting slight refractive index changes under conditions of unknown polarization state. It is argued that an insignificant modification of the tilted fiber Bragg grating (TFBG) structure and selecting the appropriate spectral region allows us to accurately track changes in the refractive index. It has also been proven that the method can be easily made insensitive to temperature and that the sensitivity to changes in the polarization plane of the input light can be significantly reduced, which is crucial in later practical applications. Analytes in the form of an aqueous glucose solution were used to calibrate the sensor. The proposed method, based on perpendicular tilted fiber Bragg grating (P-TFBG), has a wide range of universality because its development and slight modification will enable the detection of glucose, pathogens, and viruses.
