The Use of Tapered FBG Sensor for Characterizing Carbon Dioxide Gas

Abstract

Carbon dioxide gas or gas with a symbol is a combustion gas that can have a negative impact on the Earth and the health of living things. This article aims to know the meaning of carbon dioxide gas, Know the understanding and how fiber taper works, Know the use of fiber taper to detect optical properties in carbon dioxide gas, Know the advantages and disadvantages of fiber taper. This scientific paper uses the journal review method. The way a fiber taper works begins when light is directed at the fiber taper, which reduces the optical power of the light and produces a smaller critical angle. By reducing this critical angle, light exits the optical fiber and the intensity passing through the taper fiber is also low. This discussion uses the fiber taper region as a medium and changes the refractive index of the media around the taper, Fiber taper has several advantages, namely it is widely used in various photonic applications, reduces optical power loss, changes the size and shape of the light space in optical fiber, and can be produced with different profiles. In addition to advantages, optical fiber also has disadvantages, namely there is a possibility of power loss during the tapering process, prone to physical damage, requires complex handling, susceptible to temperature, pressure.
