Studies of short pulse propagation in 1D porous silicon based photonic crystals with spatially modulated photonic band gap

We study the propagation and periodical regeneration of short laser pulses in 1D porous silicon based photonic crystals (PC) with spatially modulated photonic band gap. The effective potential of this PC is analogous to that of an optical harmonic oscillator. The results of computer simulations of this effect and optical properties of the composed PC with the corresponding photonic band gap are discussed.
