    "abstract": "The dynamics of photonic wavepacket in the effective oscillator potential is\nstudied. The oscillator potential is constructed on a base of one dimensional\nphotonic crystal with a period of unit cell adiabatically varied in space. The\nstructure has a locally equidistant discrete spectrum. This leads to an echo\neffect, i.e. the periodical reconstruction of the packet shape. The effect can\nbe observed in a nonlinear response of the system. Numerical estimations for\nporous-silicon based structures are presented for femtosecond Ti:Sapphire laser\npump.",
