Microstructured Polymer Optical Fibers

Journal of Lightwave Technology, 2009
The fabrication, materials, properties and applications of microstructured polymer optical fibers are reviewed. Microstructured polymer optical fibers formed the basis of extensive work on the physics of microstructured fibers, and an outline of the contribution to the wider field of microstructured fibers is also presented.

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.

Hollow-core microstructured polymer optical fiber

Optics Letters, 2006
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.

Localized biosensing with Topas microstructured polymer optical fiber

Optics Letters, 2006
We present what is believed to be the first microstructured polymer optical fiber (mPOF) fabricated from Topas cyclic olefin copolymer, which has attractive material and biochemical properties. This polymer allows for a novel type of fiber-optic biosensor, where localized sensor layers may be activated on the inner side of the air holes in a ...

A microstructured polymer optical fiber biosensor

2006 Conference on Lasers and Electro-Optics and 2006 Quantum Electronics and Laser Science Conference, 2006
We demonstrate selective detection of fluorophore labeled antibodies from minute samples probed by a sensor layer of the complementary biomolecules immobilized inside the air holes of microstructured Polymer Optical Fibers.

Future directions for microstructured polymer optical fibers

SPIE Proceedings, 2004
Microstructured Polymer Optical Fibers (MPOF) were first made in 2001, and subsequent development has aimed at exploiting the material and design opportunities they present. Most effort has been focused on developing approaches for high bandwidth MPOF, and investigating the properties of multimode microstructured fibers.

Numerical aperture in microstructured polymer optical fibers

SPIE Proceedings, 2005
Microstructured or 'air-clad' fibers, with air holes surrounding a large core, have demonstrated much wider light acceptance angles than conventional fibers. Recently, a new method employing leaky modes has been used to determine the numerical aperture in highly multimode air-clad microstructured fibers.
