Nonlinearity in holey optical fibers: measurement and future opportunities

Abstract

Holey fibers combine two-dimensional microstructuring with one-dimensional longitudinal propagation, resulting in fibers with tailorable dispersive and nonlinear properties. We measure the effective nonlinearity of a typical holey fiber. The small effective area that is possible in this type of fiber significantly enhances its effective nonlinearity relative to standard fiber.

Specialty Fiber Coupler: Fabrications and Applications

“…Light is guided in the core by the array of air holes made around a central defect acting as the core. By adjusting the structure of the air holes, interesting characteristics of the PCF can be achieved such as endlessly single mode operation [13], anomalous dispersion [14], large single-mode area [15], and high nonlinearity [16]. Most of these features of PCF are desirable in optical communication systems as is well-known.…”

Methodology of splicing large air filling factor suspended core photonic crystal fibres

“…Although strongly demanded, such splices are still one of the fundamen− tal issues for realistic PCF applications due to the completely different inner structure of SMFs and small core and/or large air filling factor PCFs which are considered for different appli− cations, such as gas and liquid spectroscopy [1], surface−plas− mon−resonance [2], nonlinear exploitation [3][4][5], sensors [6] including hybrid system PCFs air−holes filled with liquid crystal [7][8][9], fibre lasers [10] and others.…”
