“…The 2D-chiroptical response, producing high g lum of CP laser emission, offers us a promising route to construct novel chiroptical devices . Specifically, the DCMCs with strong LB would enable the generation of tunable chiral signals based on the thermo-responsivity of their effective LB index (Δ n ) . With temperature increases, the electron cloud will be redistributed over ICT dye molecules within the β-CD cavities, which results in a molecular configuration that is more polar and anisotropic.…”

Circularly polarized (CP) lasers hold tremendous potential for advancing spin information communication and display technologies. Organic materials are emerging candidates for highperformance CP lasers because of their abundant chiral structures and excellent gain characteristics. However, their dissymmetry factor (g lum ) in CP emission is typically low due to the weak chiral light matter interactions. Here, we presented an effective approach to significantly amplifying g lum by leveraging the intrinsic 2D-chiroptical response of an anisotropic organic supramolecular crystal. The organic complex microcrystal was designed to exhibit large 2Dchiroptical activities through strong coupling interactions between their remarkable linear birefringence (LB) and high degree of fluorescence linear polarization. Such 2D-chiroptical response can be further enhanced by the stimulated emission resulted from an increased degree of linear polarization, yielding a nearly pure CP laser with an exceptionally high g lum of up to 1.78. Moreover, exploiting the extreme susceptibility of LB to temperature, we demonstrate a prototype of temperature-controlled chiroptical switches. These findings offer valuable insights for harnessing organic crystals to facilitate the development of high-performance CP lasers and other chiroptical devices.

“…Sagnac Interferometer. This method of measurement compares two light waves that are transmitted against each other [93,94]. If the frequencies of electromagnetic waves are different, the phase shift between them is changing with the time.…”

“…As a result, we can measure the shift of the interference spectrum of the PMF. The sensitivity of 1.38 nm/°C was achieved within the temperature range 21-50°C [93] or even 18.27 nm/°C within the range 0-40°C [95]. However, a wide spectrum of research around this type of temperature measurement seems to be limited to temperatures of around 120°C [96].…”

The paper deals with the overview of fiber optic methods suitable for temperature measurement and monitoring. The aim is to evaluate the current research of temperature measurements in the interval from temperature close to 0 up to 1000°C. Since the measuring chain is a functional combination of optical methods, optical fiber properties, and other photonic elements together with control electronic circuits, it is necessary to find a suitable compromise between the chosen measurement method, measuring range, accuracy, and resolution. Optical fiber sensors can be used in cases where standard electrical measurement methods cannot be used. These may be areas with high electrical and magnetic interference or critical areas. Therefore, there is intensive development of optical and fiber optic methods based on blackbody and greybody radiation, luminescence, fiber Bragg gratings (FBGs), and interferometers.
