摘要

浮在水面上的薄膜表面上出现了光诱导浮雕图案。这些结构的长度为几毫米，宽度为 33 微米。照射光的强度和偏振都会改变所生成图案的特征。光诱导结构化同时是偶氮苯单元光异构化产生的可逆物质传输和分子自组织过程的结果。这些结构可用作波导或光栅，在空气/液体界面上实现短距离或长距离的光耦合。波导的制造可扩展到任何液体基底。

Surface relief structures for light coupling at air/liquid interface

Relief patterns were photoinduced on the surface of a thin film floating on water. The structures have a length of several millimeters with a width of 33 μm. Both the intensity and the polarization of the irradiated light change the characteristics of the generated patterns. The light induced structuration is the result of simultaneously a reversible material transport originated by photoisomerization of azobenzene units and a process of self-organization of the molecules. The structures were used as waveguide or grating to couple light at the air/liquid interface on a short or long distance. The fabrication of waveguides can be extended to any liquid substrates.
