• Sb-based metamorphic DBR membranes are developed for InP-based vertical cavity laser applications. The reflectivity of the metamorphic DBR membrane is compared to the reflectivity of a lattice-matched DBR to characterize the optical quality of the DBR membrane. The metamorphic interface between InP and the III-antimonides is found to degrade the reflectivity of the DBR. Therefore, the growth temperature for the metamorphic DBR is optimized in order to obtain highly reflective (>99.8%) III-Sb thin-film membranes. •Growth of III-Sb metamorphic DBRs on InP for vertical cavity lasers is explored.•The DBR membranes are isolated from the substrate to study the metamorphic interface.•The metamorphic interface is characterized using reflectivity of the DBR and TEM•Optimum growth temperature for highly-reflective DBR membranes is found to be 450°C.
