Erbium doped highly birefringent microstructure fiber

In this article a novel highly-birefringent erbium-doped microstructured optical fiber is presented. The modal properties of the structure are analyzed numerically using a fully vectorial finite difference method. The emission properties of the structure have also been investigated. The emission at 1550 nm has been measured. The realised fiber can find potential applications in metrology or telecommunication optical systems.
