Abstract

An index-guiding photonic crystal fiber (PCF) has a solid core surrounded by a holey cladding region. A typical index-guiding PCF is fabricated by stacking silica capillaries periodically in a hexagonal close packed array and replacing the central capillary with a solid silica rod of the same outer dimension. Index-guiding photonic crystal fibers with appropriate structural parameters support the fundamental and second order modes over a practically infinite wavelength range. The polarization principal axes and mode field patterns of the modes can be made stable by having different size air-holes along the orthogonal directions.

In this seminar, a general reviews about FBGs, PCFs and their fibre sensor applications will be given. Especially the potential applications of two-mode PCFs and other types of PCFs are discussed extensively.
