Room-temperature continuous wave emission of II-VI laser diodes

ZnMgSSe is a suitable material for the cladding layer of II-VI compound laser diodes because both the bandgap energy and the lattice constant can be controlled. Furthermore, it is found that this material has good thermal stability. Both n-type and p-type ZnMgSSe have been successfully obtained, and showed good properties for fabricating laser diodes. Utilizing this novel material, we fabricated several laser structures. Recently, room temperature continuous wave operation was achieved with ZnCdSe/ZnSe/ZnMgSSe separate-confinement-heterostructure. A review of the recent progress of blue laser diodes fabricated in our laboratory and those fabricated by other research groups is presented.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
