Monolithic integration of 940 nm AlGaAs distributed Bragg reflectors on bulk Ge substrates

Yunlong Zhao, Jia Guo, Markus Feifel +8

High quality 940 nm Al${}_x$Ga${}_{1-x}$As n-type distributed Bragg reflectors (DBRs) were successfully monolithically grown on off-cut Ge (100) substrates. The Ge-DBRs have reflectivi…
