| Abstract(in English) | To suppress lasing in higher order transverse modes and improve kink levels in ridge-type 980-nm fiber pump semiconductor lasers, a novel ridge structure with optical antiguiding layers for horizontal transverse modes is proposed, and lasing characteristics are theoretically analyzed from the viewpoint of a step and a space in the optical antiguiding layers. In the proposed ridge structure, kink levels are improved by suppressing spatial hole burning and lowering optical gains for higher order transverse modes, with an increase in the step of the antiguiding layers, which are located at both sides of an active region below a mesa. Also, threshold current is reduced due to concentration of injected current into the active region below the mesa. It is also found that an optimum space exists to obtain the highest kink level. |
