9 We report a simple fabrication technique of polymer microfibers with high surface smoothness and length uni10 formity using a molten polymethylmethacrylate in conjunction with direct drawing technique. With the aid of 11 fabricated polymer microfibers, we successfully demonstrate a new splicing technique via a two-step process. The 12 fabricated microfibers with diameter of 1.5 μm and length ...
We have fabricated microstructured polymer optical fibers that guide light in a hollow core using the photonic bandgap mechanism. The hollow core allows the use of polymer fibers to be extended to wavelength ranges where material absorption typically prohibits their use, with attenuation lower than the material loss observed in the infrared. The fabrication method is similar to other microstruc...
We propose a new hole-assisted polymer optical fiber design to eliminate the influence of dopant diffusion and to increase the UV writing efficiency in fiber Bragg grating inscription. The optical waveguide is formed inside a solid core surrounded by a ring of 3 large air holes in enhanced UV photosensitive PMMA with double-cladding. We determined a map of the single-mode and multi-mode phase t...
A fiber fuse phenomenon in polymer optical fibers (POFs) has recently been observed, and its unique properties such as slow propagation, low threshold power density, and the formation of a black oscillatory damage curve, have been reported. However, its characterization is still insufficient to well understand the mechanism and to avoid the destruction of POFs. Here, we present detailed experim...
This article presents a review of the fuse effect in polymer optical fibers (POFs) and its sensing applications. First, propagation mechanisms characteristics POF are discussed, showing that threshold power velocity much lower than those silica fiber fuse. In addition, it is shown main unique advantages capability transmitting signal as well electrical conductivity carbonized oscillatory path c...
We demonstrate wide-band ultrafast optical pulse generation at 1, 1.5, and 2 μm using a single-polymer composite saturable absorber based on double-wall carbon nanotubes (DWNTs). The freestanding optical quality polymer composite is prepared from nanotubes dispersed in water with poly(vinyl alcohol) as the host matrix. The composite is then integrated into ytterbium-, erbium-, and thulium-doped...
