Single crystal fibers (SCF) are considered to be a combination of bulk crystals and conventional fibers, thereby possessing the stable physical and chemical properties accompanied with excellent waveguide properties. This paper gives a detailed introduction to the development history of single crystal fibers, including the evolution of the growth technique and the optimization of the growth process. Laser-heated pedestal growth (LHPG) and Micro-pulling-down (μ-PD) methods are considered to be the most widely used growth techniques for growing single crystal fibers, and the advantages of the two methods are also introduced in detail. The second part of this paper describes the characterization of single crystal fibers, including diameter fluctuation, crystal quality and optical losses. A series of cladding approaches for SCF, such as magnetron sputtering, sol-gel, liquid phase epitaxy, co-drawing LHPG, ion implantation and micro-structure cladding will be reviewed. In addition, the research status of single crystal fiber laser and single crystal fiber sensor are also summarized in view of the current research foundation.

“…In addition to such a problem, the need to characterize systems which cannot be directly accessed has fostered the research for effective schemes for indirect quantum probing [1,2]. Quantum thermometry, i.e., the estimation of the operating temperature of a quantum system, offers interesting opportunities for the design and application of indirect probing strategies, which would be useful for the characterization and control of temperature of microand nanodevices [3][4][5][6][7].…”

The dimensionality of a thermometer is key in the design of quantum thermometry schemes. In general, the phenomenology that is typical of qubit-based quantum thermometry does not apply to infinite-dimensional ones. We analyze the dynamical and metrological features of nonequilibrium Gaussian quantum thermometers: On one hand, we highlight how quantum entanglement can enhance the readiness of composite Gaussian thermometers; on the other hand, we show that nonequilibrium conditions do not guarantee the best sensitivities in temperature estimation, thus suggesting the reassessment of some of the working principles underpinning quantum thermometry.

“…1,2 Conventional contact temperature measurements are based on the principle of either the thermal expansion of materials or the Seebeck effect, for example liquid-lled glass thermometers and thermocouples. 3,4 Therefore, they cannot be applied in submicron scale or harsh environments, such as high-voltage power plants, microcircuits, and intracellular liquids. [5][6][7] Compared with contact thermometers, optical temperature measurement has the unique advantages of non-contact measurement and large-scale imaging, 8 which are based on particular parameters of luminescence such as the peak position, line width, uorescence intensity, uorescence lifetime, and FIR.…”
