A photonic crystal fiber is an optical fiber which obtains its waveguide properties not from a spatially varying glass composition but from an arrangement of very tiny and closely spaced air holes which go through the whole length of fiber. There are also so-called photonic bandgap fibers with a totally different guiding mechanism, based on a photonic bandgap of the cladding region. The latter mechanism even allows guidance in a hollow core, such that most of the power propagates in the central hole. Such air-guiding hollow-core photonic crystal fibers can have a very low nonlinearity and a high damage threshold.
