精彩书摘

　　1.3.1 Solid-core fibers
　　Index-guiding PCFs， with a solid glass region within a lattice of air-holes， offer a lot of new opportunities， not only for applications related to fundamental fiber optics. These opportunities are related to some special properties of the photonic crystal cladding， which are due to the large refractive index contrast and the two-dimensional nature of the microstructure， thus affecting the birefringence， the dispersion， the smallest attainable core size， the number of guided modes and the numerical aperture and the birefringence. Highly birefringent fibers Birefringent fibers， where the two orthogonally polarized modes carried in a single-mode fiber propagate at different rates， are used to maintain polarization states in optical devices and subsystems. The guided modes become birefringent if the core microstructure is deliberately made twofold symmetric， for example， by introducing capillaries with different wall thicknesses above and below the core. By slightly changing the air-hole geometry， it is possible to produce levels of birefringence that exceed the performance of conventional birefringent fiber by an order of magnitude. It is important to underline that， unlike traditional polarization maintaining fibers， such as bow tie， elliptical-core or Panda， which contain at least two different glasses， each one with a different thermal expansion coefficient， the birefringence obtainable with PCFs is highly insensitive to temperature， which is an important feature in many applications. An example of the cross-section of a highly birefringent PCF is reported in Fig. 1.6.
　　Dispersion tailoring
　　The tendency for different light wavelengths to travel at different speeds is a crucial factor in the telecommunication system design. A sequence of short light pulses carries the digitized information. Each of these is formed from a spread of wavelengths and， as a result of chromatic dispersion， it broadens as it travels， thus obscuring the signal. The magnitude of the dispersion changes with the wavelength， passing through zero at 1.3 μm in conventional opticalfibers.
