Abstract: In this study, high-refractive-index fluorotellurite glass microspheres (FTG-MSs) were fabricated using a high-temperature melt-quenching technique. The resulting microspheres exhibited good ...
Abstract: In this paper, a novel refractive index (RI) sensor based on the soliton self-frequency shift (SSFS) in tellurite photonic crystal fiber (TPCF) is proposed. RI sensing in the mid-infrared ...
