All Fiber-Based Optical Transmitters and Switching Technologies

摘要

This report describes a two-year research effort directed toward theunderstanding of very robust fiber lasers utilizing Yb:Er co-doped fiber for the gain medium. We have achieved stable CW output utilizing in-fiber Bragg grating technology. Of the greatest importance is the effectiveness of Yb:Er co-doped fibers for the purpose of suppressing ion-pair induced Q-switching and for the enhancement of pumping in high gain fibers.
