目前，锁模光纤激光器正朝着更高的脉冲能量和更短的脉冲持续时间方向发展。这一进展的一个关键推动因素是发现了新型可饱和吸收体（SA），如碳纳米管（CNT）和石墨烯。近年来，碳纳米管作为SA的特殊性能得到了广泛的研究。石墨烯，一个原子厚的平面片的碳原子排列成六边形晶格，最近已提出作为替代CNT在几个光子学应用。在这里，我们提出了一种使用光学沉积技术将石墨烯集成到光纤套圈中的方法，该方法也被用于直接在光纤边缘的芯上和锥形光纤中沉积CNT。我们调查和比较的光学性质的CNT-SA和石墨烯-SA制造这种光学沉积技术。在全光纤环形腔激光器结构中，掺铒光纤实现了类孤子锁模激射。(C)2010年美国光学学会
Mode-locked fiber lasers are currently undergoing a significant evolution towards higher pulse energies and shorter pulse durations. A key enabler in this progress has been the discovery of novel saturable absorbers (SA) such as carbon nanotubes (CNT) and graphene. The exceptional properties of CNTs as SA have been extensively studied in recent years. Graphene, a one atom thick planar sheet of carbon atoms arranged into a hexagonal lattice, has been recently proposed as an alternative to CNTs in several photonics applications. Here, we propose a method for the integration of graphene into a fiber ferrule using an optical deposition technique, which has been also employed for the deposition of CNT directly on the core of a fiber edge and in tapered fibers. We investigate and compare the optical properties of CNT-SA and graphene-SA fabricated by this optical deposition technique. Soliton-like, mode-locked lasing is confirmed using an erbium doped optical fiber in an all-fiber ring cavity laser configuration. (C) 2010 Optical Society of America
