As of the writing of this work, generation of white light continuum (WLC) in hollow-core photonic crystal fibers (HCPCF) filled with gases is being thoroughly researched. These structures allow the possibility of adjusting light generation properties by changing the fill gas pressure. Kagomé hollow-core PCF and silica capillaries have been used to study the nonlinear effects in gases as they facilitate exploring these weak properties. In this paper, we numerically analyze the generation of WLC in a new type of hollow-core PCF, called negative curvature hollow-core fiber (NCHCF), itself filled with different inert gases. We show that this type of fiber is a better alternative to the Kagomé and capillary fibers because it exhibits low losses and the WLC spectrum generated presents a relatively flat wavelength span from around 400[Formula: see text]nm to 2400[Formula: see text]nm under certain circumstances.

AbstractIn this work, a novel optical fiber sensor capable of measuring both the liquid level and its refractive index is designed, manufactured and demonstrated through simulations and experimentally. For this, a silica capillary hollow-core fiber is used. The fiber, with a sensing length of 1.55 mm, has been processed with a femtosecond laser, so that it incorporates four holes in its structure. In this way, the liquid enters the air core, and it is possible to perform the sensing through the Fabry–Perot cavities that the liquid generates. The detection mode is in reflection. With a resolution of 4 μm (liquid level), it is in the state of the art of this type of sensor. The system is designed so that in the future it will be capable of measuring the level of immiscible liquids, that is, liquids that form stratified layers. It can be useful to determine the presence of impurities in tanks.
