Abstract

Polyurethane bearing an aminonitroazobenzene was synthesized for fabricating the diffraction grating on the film surface. Two beam coupling method was employed for fabricating the diffraction grating. The dynamics of diffraction grating was studied in term of the variation of the diffraction efficiency. The long-term stability of the diffraction efficiency was also investigated.
