“…The controlling technologies of conducting light in optical fibers play significant roles in both optical fiber communication systems and fiber sensing systems. The traditional controlling technologies are mainly based on electricity, mechanics or magnetism [1][2][3], which are technically mature and stable but sensitive to electromagnetic interference and lace of compactness. As a neotype technology, the all-optical controlling technology has been widely studied due to its small volume, immunity to electromagnetic interference and compatibility with optical networks [4][5][6][7][8][9][10][11][12][13].…”

An all-optical controlled attenuation effect in an all-fiber system based on ionic liquid-filled photonic bandgap fiber (ILF-PBGF) is observed and demonstrated. The ILF-PBGF is formed by infusing a temperature-sensitive high-index ionic liquid into the cladding holes of the microstructured optical fiber. With the interactions between the controlling light and the highindex liquid columns, the bandgap drift of ILF-PBGF was observed, and an extinction ratio of about 8 dB was obtained at 1540 nm. Experimental investigations reveal that the attenuation is arose from the refractive index changes induced by thermal effect of the functional material.

“…The interaction of evanescent fields of light propagating in waveguiding structures with a covering medium has been used in numerous applications, including sensing devices [1][2][3], tunable optical filters [4,5], and the excitation of fluorescent dyes in thin layers with high spatial resolution [6]. Because of the variety of application possibilities in many scientific fields it has become inevitable to properly design the spatial shape and propagation constants of guided modes, which also influences their evanescent parts and allows for tailoring them for specific applications.…”

The sensitivity of an integrated optical sensing device can be enhanced by coating it with a high refractive index layer, while both incoupled intensity and spatial resolution are maintained. The potential for enhanced sensing is demonstrated using titanium indiffused waveguiding structures in LiNbO(3) coated with a TiO(2) film. To the best of our knowledge, it could be measured for the first time that the outcoupled intensity at the surface was enhanced by a factor of 12-15 while keeping the penetration depth of the evanescent field constant of the order of only a few tens of nanometers. The evanescent fields of the guided modes were measured and characterized with a scanning near-field optical microscope and are in accordance with the numerical simulations.
