HIGHLIGHTS
- who: Amirhossein, Tehranchi and Raman, Kashyap from the Department of Electrical Engineering, Polytechnique Montreal, University of Montreal, Montreal, QC H C , Canada have published the research work: Extremely Efficient DFB Lasers with Flat-Top Intra-Cavity Power Distribution in Highly Erbium-Doped Fibers, in the Journal: Sensors 2023, 23, 1398. of /2023/
- what: In this paper for a given background fiber loss first the optimum intra-cavity signal powers for various pump powers are numerically calculated. In this paper, to maximize the laser efficiency and unidirectionality, an optimum coupling coefficient for highly EDF-DFB lasers . . .
