Application of quasiperiodic structures to compression of ultrashort laser pulses

Photonic band gap (PBG) crystals provide an opportunity to compress short light pulses and to control their phase. The present paper is devoted to the theoretical analysis of laser pulse compression in quasiperiodic nonsymmetric and symmetric Fibonacci-like structures, which are found to exhibit PBGs as well, provided the number of layers or the depth of refraction index modulation are large enough. One of the main advantages of compressors based on one-dimensional linear Fibonacci structures is that the length of dispersion spreading for chirped light pulses is about ten times less than that for periodic structures of the same size.
