Direct Writing of Fiber Bragg Grating in Microstructured Polymer Optical Fiber
IEEE Photonics Technology Letters, 2012 We report point-by-point laser direct writing of a 1520-nm fiber Bragg grating in a microstructured polymer optical fiber (mPOF). The mPOF is specially designed such that the microstructure does not obstruct the writing beam when properly aligned. A fourth-order grating is inscribed in the mPOF with only a 2.5-s writing time.

Optics Letters, 2009 Ultrahigh-resolution fiber-optic image guides--fused image fiber, faceplate, and taper--were fabricated by using microstructured polymer optical fiber (MPOF) preforms composed of two polymers: polymethylmethacrylate and polystyrene. The pixel diameter in the resultant MPOF-based image guides was as small as 3 microm.

Transmission of terahertz radiation using a microstructured polymer optical fiber
Optics Letters, 2008 A hollow-core microstructured polymer optical fiber was analyzed in the terahertz (THz) region. Spectral analysis of time domain data shows propagation of THz waves in both the hollow-core and the microstructured cladding with a time delay of approximately 20 ps. The frequency range and shift of the transmission bands between different sized waveguides

Fabrication of microstructured polymer optical fiber preform
SPIE Proceedings, 2006 We report a new technology to fabricate microstructured polymer optical fiber (MPOF, also named polymer photonic crystal fiber, pPCF) preform rods by in-situ polymerization of monomer in a mould. Series of pPCF preform rods including elliptic core fiber preform rod, single-mode fiber preform rod and ring-type holes structured preform rods have been ...

Sensing characteristics of birefringent microstructured polymer optical fiber
SPIE Proceedings, 2011 We experimentally studied several sensing characteristics of a birefringent microstructured polymer optical fiber. The fiber exhibits a birefringence of the order 2×10 -5 at 1.3 μm because of two small holes adjacent to the core. In this fiber, we measured spectral dependence of phase and group modal birefringence, bending losses, polarimetric ...

Hollow-core microstructured polymer optical fiber
Optics Letters, 2006We 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.
