摘要：

A new technique for the fabrication of freestanding poled polymer films that uses a metallic film as the lifting-off layer is reported. This technique is used to make low-transmission-loss bulk periodic synthetic-crystals structures that satisfy a quasi-phase-matching condition for second-harmonic generation. Efficiency of the order of 10(-2)% is obtained for a thickness of 150 mum. The theoretical basis for determining the optimum phase-matching angle to maximize the second-harmonic conversion efficiency is discussed.
