Paper Abstract

In conventional optical fibers the light guiding and other optical properties are mainly controlled by the index profile as given by the composition of the doping materials. In this case technological and material properties limit the design flexibility of the optical properties. For example, it is not possible to shift the region of anomalous dispersion to wavelengths shorter than the zero dispersion value of silica. In contrast to these conventional fibers, for microstructured or photonic crystal fibers (PCF) the optical properties are determined by the size, distribution and geometry of the air holes running the entire length of the fiber. Variations of the geometrical parameters offer a wide flexibility in designing different optical properties. It is possible, for example, to modify numerical aperture and mode field area over wide ranges or to shift the zero dispersion wavelength down to the visible spectral region. In the case of hollow core fibers (photonic bandgap fibers) the interaction of the guided light with the glass material is reduced and allows the transmission of higher intensities with reduced nonlinear effects.
