Light induced self-written waveguides (LISWs) with unique elongation characteristics and low optical loss are formed in a monodispersed polyisoprene solution using a low-power laser photopolymerization process, while their light transmission characteristics are exemplified in the flexible interconnection of two single-mode optical fibers operating in the visible/near infrared wavelengths. The LISWs formed exhibit rubbery properties, allowing extensibilities upon cases from 400% to 800%, while still retaining significant optical transmission. The rubber elasticity enables sustaining LISWs at stressed lengths longer than 500 µm propagation losses from 1.0 to 2.9 dB/mm.
利用低功率激光光聚合工艺，在单分散聚异戊二烯溶液中形成了具有独特伸长特性和低光损耗的光诱导自写波导（LISW），同时在工作于可见光/近红外波长的两根单模光纤的柔性互连中展示了它们的光传输特性。所形成的LISW具有橡胶特性，在拉伸情况下可伸长400%至800%，同时仍保持显著的光传输。橡胶弹性使LISW能够在应力长度超过500 µm时维持，传播损耗为1.0至2.9 dB/mm。
