Highly doped 1.55 µm Ga x In 1- x As/InPdistributed Bragg reflector stacks

Abstract
The authors have investigated 20 period lattice matched mirror stacks doped to 5 × 1018 cm-1 and 1019 cm-1 at 1.55 µm in GaxIn1-xAs/InP and have obtained greater than 95% reflectivity over 100 nm and peak reflectivities up to 98%.
