Abstract Fabrication of microfiber saturable absorbers (SA) is a tedious process. This work demonstrates a simplified method of microfiber SA fabrication by integrating graphene oxide/polymethylsiloxane (GO/PDMS) using dip-coating technique. The idea is to enhance light-matter interaction between graphene and propagating light modes within the microfiber by enhancing the binding strength and proximity of the graphene-polymer composite to the microfiber. The implementation of GO/PDMS SA in an erbium-doped fiber laser cavity has successfully generated ultrashort pulses with pulse duration of 629 fs in the C-band emission region. The success of this work contributes to better insight towards simplifying the fabrication technique of microfiber SAs.

用于锁模光纤激光器的浸渍涂层结合氧化石墨烯聚合物复合材料的饱和吸收体

摘要 超细纤维可饱和吸收体 (SA) 的制造是一个繁琐的过程。这项工作展示了一种通过使用浸涂技术集成氧化石墨烯/聚甲基硅氧烷 (GO/PDMS) 的简化微纤维 SA 制造方法。这个想法是通过增强石墨烯-聚合物复合材料与微纤维的结合强度和接近度来增强石墨烯和微纤维内传播光模式之间的光物质相互作用。在掺铒光纤激光器腔中实施 GO/PDMS SA 已成功在 C 波段发射区产生脉冲持续时间为 629 fs 的超短脉冲。这项工作的成功有助于更好地了解简化超细纤维 SA 的制造技术。
