我们提出的证据，光诱导生长的纤维图案成光聚合树脂。通过将紫外（UV）激光聚焦到所使用的光聚合树脂中来实现单个或多个纤维的光学生长。纤维生长是由于树脂在光照射时的光聚合产生树脂折射率的增加的效应，树脂折射率的变化反过来限制了光传播到波导型纤维结构中。我们还观察到，在特定条件下，两个光学生长的独立光纤可以合并成单个光纤。我们已经研究了这种光纤结构的光学生长现象对所有实验参数的依赖性，包括用于聚焦光的透镜的数值孔径（NA）、光功率和曝光时间。
We present evidence of optically-induced growth of fiber patterns into a photopolymerizable resin. Optical growth of a single or multiple fibers is achieved by focusing an ultraviolet (UV)-laser light into the photopolymerizable resin used. The fiber growth is due to an effect in which photopolymerization of the resin upon light irradiation produces an increase of the resin refractive index, the change of which, in turn, confines the light propagation into waveguide-type fiber structures. We have also observed that two optically grown independent fibers can merge to form a single fiber under specific conditions. We have studied the dependence of this optical growth of fiber structures phenomena on all the experimental parameters, including the numerical aperture (NA) of the lens used to focus the light, the light power, and the exposure time.
