A new design approach for fibre DFB lasers with improved efficiency
The standard DFB laser optimisation method is critically investigated and a new design approach based on the effective cavity length is presented. By applying this method in a Erbium-Ytterbium co-doped fibre, pump-to-signal conversion ratio is increased by 40% for the same total device length and pumping conditions. The laser with proposed design is produced and the theoretical results are verified by the experimental work.

Abstract

The standard DFB laser optimisation method is critically investigated and a new design approach based on the effective cavity length is presented. By applying this method in a Erbium-Ytterbium co-doped fibre, pump-to-signal conversion ratio is increased by 40% for the same total device length and pumping conditions. The laser with proposed design is produced and the theoretical results are verified by the experimental work.
