Abstract

We report experimental results on the continuous-wave lasers based on a small core erbium-doped holey fiber. In a simple Fabry-Pérot-type cavity with high output coupling, we demonstrate low-threshold (0.55 mw) high slope-efficiency (57.3%) operation confirming both the quality and exceptionally high gain efficiency of the fiber. In an all-fiber ring cavity where the cavity loss is reduced, we show that it is possible to achieve a low-threshold laser with extremely wide tunability (> 100 nm around 1550 nm). Our results illustrate some of the unique opportunities provided by active small core holey fibers.
