OPTIC FIBER WITH CARBON NANO-STRUCTURE LAYER, FIBER OPTIC CHEMICAL SENSOR AND METHOD FOR FORMING CARBON NANO-STRUCTURE LAYER IN FIBER CORE

摘要

The invention relates to an optic fiber having a core in which carbon nano-structures are formed at a predetermined locus, a fiber optic chemical sensor using the optic fiber, and a method of forming the carbon nano-structure layer in the core of the optic fiber. The invention utilizes gas refractive index and the adsorption sensitivity of particles on the surface of the carbon nano-structure layer, and uses the carbon nano-structure layer in the core of the optic fiber as a sensor for particles of gas, liquid and the like.
