A VCSEL includes a substrate; a first mirror stack over the substrate; an active region having a plurality of quantum wells over the first mirror stack; and a second mirror stack over the active region, wherein either or both of the first and second mirror stacks include alternating layers of II-VI and III-V compounds, and wherein said II-VI compound is selected from the group consisting of ZnCdSe, ZnSeTe and ZnMgSe, and said III-V compound is selected from the group consisting of InGaAsP, InAlGaAs and InP. Such a mirror stack is especially useful for a long-wavelength VCSEL. |
