| Abstract: | A cladding mode resonant specialty optical fiber comprising a double cladding structure is proposed.The specific fiber has a thin and low refractive index inner cladding.Based on the coupled mode theory,a core mode can be resonantly coupled to a cladding mode,and then a band-reject spectrum can be obtained.We mainly introduce the fabrication technology,operation principle of the specific fiber and demonstrate its senor applications in bend,solution refractive index(RI) and RI/temperature dual parameters.As ... |
