摘要

The all-optical poling technique allows writing non-centrosymmetric gratings that are automatically phase-matched for second-harmonic generation by purely optical means. One drawback of all-optical poling in organic materials is the poor stability of the recorded gratings due to thermal and/or photo-induced molecular randomization. Using a two beam technique, we have compared the all-optical poling process in different kinds of polymers with Disperse Red 1 dye: guest-hosts with hydrogen-bond interactions between the guest dye and the host polymer and a side-chain polymer in which the dyes are attached through covalent bonds. We show that in the investigated polymer systems, hydrogen-bonded guest-hosts are capable of surpassing the stability of side-chain polymers.
