Abstract:

We report the first successful monolithic integration of AlGaAs distributed Bragg reflectors (DBR) on virtual Ge substrates via aspect ratio trapping ─ the first and crucial step towards the successful integration of VCSELs on Si platforms. The ART-based DBRs have reflectivity spectra comparable to those grown on bulk GaAs substrates.
