Abstract

ABSTRACT By incorporating double-ring cavities and a piece of un-pumped Er3+-doped fiber (EDF) as a saturable absorber, we report a single-longitude-mode EDF fiber laser at C-band. The single-longitude-mode is obtained, the first time, by inserting only two subring cavities in either serial connection or parallel connection. The fiber laser has an optical signal-to-noise-ratio of 34.5 dB and a maximum power fluctuation of less than 1.3% for 1-hr operation. It was then modulated up to 10 Gbit/s by using an electro-optic modulator for eye diagrams, compared to back-to-back transmission. Such a compact and low-cost fiber laser is potential for high-speed optical communication.

单经模光纤激光器在串行/并行连接中仅使用两个子腔实现

本文报道了一种c波段单经模EDF光纤激光器，该激光器采用双环腔和一段未抽运Er3+掺杂光纤(EDF)作为可饱和吸收体。通过在串联或并联连接中只插入两个子腔，首次获得了单经度模态。光纤激光器工作1小时的光信噪比为34.5 dB，最大功率波动小于1.3%。然后，与背靠背传输相比，使用用于眼图的电光调制器将其调制到10gbit /s。这种紧凑、低成本的光纤激光器在高速光通信中具有潜力。

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
