Optical fibres have for almost three decades been fabricated of solid glass. It was, therefore, a radical change that took place, when researchers in the late 90's started to fabricate hair-thin optical fibres with numerous microscopic air holes running along the length of the fibres. These microstructured fibres did not only mark the introduction of tailored materials with unique spectral properties in fibre optics, but it also opened the perspective of the applicability of photonic bandgap materials at optical wavelengths. In this respect, a completely new guiding mechanism was...
