Distributed Bragg reflectors (DBR) were grown by molecular beam epitaxy using wide-gap ZnMgSe/ZnCdSe and ZnMgSe/ZnSeTe systems. The refractive indices of the component Zn alloys were determined by prism coupler measurements for λ = 632.8 nm as a function of composition, prior to fabrication. The energy gap and refractive index of the ZnSe1-xTex alloy was also determined at 632.8 and 1300 nm as a function of Te concentration. The effect of composition on the energy gap at 10 K and the room-temperature refractive index at 632.8 nm of the Zn1-xMgxSe and Zn1-xBexSe systems was analyzed. The reflectivity spectra for the 20-period ZnMgSe/ZnCdSe and the 10-period ZnMgSe/ZnSeTe DBR systems are presented.
