“…The fabrication process of the germano-silicate optical fiber embedded with Au NPs in the cladding and the measurement of its SPR sensing property was described in detail in our previous work [52,70,71]. The Au NPs(cladding)-doped glass fiber coated with low refractive index polymer (SSCP Co., Ltd., Ansan-si, Kyunggi-do, South Korea, FIRON UVF PC-375, n = 1.3820 @ 852 nm) was designed to enable a light to propagate into the cladding, not into the core.…”

The effect of γ-ray irradiation on the surface plasmon resonance (SPR) sensing capability of refractive index (n = 1.418–1.448) of the silica glass optical fiber comprised of germano-silicate glass cladding embedded with Au nano-particles (NPs) was investigated. As the γ-ray irradiation increased from 1 h to 3 h with the dose rate of 1190 Gy/h, the morphology of the Au NPs and the SPR spectrum were found to change. The average diameter of Au NPs increased with the aspect ratio from 1 to 2, and the nano-particles became grown to the clusters. The SPR band wavelength shifted towards a longer wavelength with the increase of total dose of γ-ray irradiation regardless of the corresponding refractive indices. The SPR sensitivities (wavelength/refractive index unit, nm/RIU) also increased from 407 nm/RIU to 3553 nm/RIU, 1483 nm/RIU, and 2335 nm/RIU after the γ-ray irradiation at a total dose of 1190 Gy, 2380 Gy, and 3570 Gy, respectively.

“…A novel optical fiber having its cladding doped with Au nanoparticles was developed by modified chemical vapor deposition process. Absorption peaks of the optical fiber preform and the fiber appearing at 585 and 428 nm respectively, were due to surface plasmon resonance (SPR) of the incorporated Au nano-particles (NPs) in the cladding [5]. Figure 4 shows the refractive index and the propagation of light through the cladding of the fiber doped with Au NPs.…”

“…Optical absorption of the optical fibers was also measured to confirm the propagation of light and the existence of Au NPs by the cut-back method using the Optical Spectrum Analyzer. Then, to characterize SPR sensing property, optical absorption of the fiber was measured by putting small drops of the refractive index matching oil with various refractive indices (n = 1.406-1.436) on the surface [5] of the fiber. The total and detector lengths of the fiber used for the SPR measurement are 50 and 5 cm, respectively, as shown in Fig.…”

This paper reviews the development progress of optical fiber, the producing and application of the specialty optical fiber in the world. Finally it states the leading technology of optical fiber of the world. Specialty optical fibers are series of optical fiber which could satisfy special requirements. Recently, the rapidly growing need from fiber to the home (FTTH), sensors, active optical link, energy conversion and delivery and fiber laser attracts researchers and optical companies to explore more possibilities of optical fiber and some novel specialty optical fibers were invented for the efforts. Bending insensitive optical fiber with the ability of extreme 3 mm bending diameter makes it possible to use the optical fiber as the electric wire in some extremely compact devices. Higher power was achieved in the fiber laser field with the development of rare earth doped fiber. Nanomaterials such as Au particles and ZnO nanostructures were utilized to extend the application in sensors and energy conversion. Pure silica design was commercialized to improve the radiation resistance of sensors based on fiber optics.
