TL;DR: In this paper, a review of the different types and applications of photonic crystal fibers with particular emphasis on recent advances in the field is presented, with a focus on the photonic bandgap effect.

TL;DR: It is demonstrated that highly efficient evanescent-wave detection of fluorophore-labeled biomolecules in aqueous solutions positioned in the air holes of the microstructured part of a photonic crystal fiber even at wavelengths in the visible range is demonstrated.

TL;DR: In this article, a tunable bandgap guidance is obtained by filling the holes of a solid core photonic crystal fiber with a nematic liquid crystal and applying an electric field.

TL;DR: An electrically controlled photonic bandgap fiber device obtained by infiltrating the air holes of a photonic crystal fiber with a dual-frequency liquid crystal with pre-tilted molecules that enables electrical control of the spectral position of the bandgaps towards both shorter and longer wavelengths in the same device.

TL;DR: In this article, the waveguiding properties of two silica-based, air-guiding photonic bandgap fiber designs are investigated with special emphasis on material effects, and the nonlinear coefficients are found to be 1-2 orders of magnitude smaller than those obtained in index-guided microstructured fibers with large mode areas.
