Designing microstructured polymer optical fibers for cascaded quadratic soliton compression of femtosecond pulses [PDF]

open access: yes, 2008
The dispersion of index-guiding microstructured polymer optical fibers is calculated for second-harmonic generation. The quadratic nonlinearity is assumed to come from poling of the polymer, which in this study is chosen to be the cyclic olefin copolymer

Microstructured optical fiber interferometric breathing sensor

open access: yesJournal of Biomedical Optics, 2012
In this paper a simple photonic crystal fiber (PCF) interferometric breathing sensor is introduced. The interferometer consists of a section of PCF fusion spliced at the distal end of a standard telecommunications optical fiber. Two collapsed regions in the PCF caused by the splicing process allow the excitation and recombination of a core and a ...

A microstructured fiber source of photon pairs at widely separated wavelengths

open access: yes, 2010
We demonstrate a source of photon pairs with widely separated wavelengths, 810 nm and 1548 nm, generated through spontaneous four-wave mixing in a microstructured fiber.

Symmetry and degeneracy in microstructured optical fibers [PDF]

open access: yesOptics Letters, 2001
The symmetry of an optical waveguide determines its modal degeneracies. A fiber with rotational symmetry of order higher than 2 has modes that either are nondegenerate and support the complete fiber symmetry or are twofold degenerate pairs of lower symmetry.
