Impact of Ge substrate Thicknesses and Epitaxy Growth Conditions on the Optical and Material Properties of Ge- and GaAs-based VCSELs

Wenhan Dong, Zeyu Wan, Yun-Cheng Yang +4

We present a comparative study of the optical and material property dependences of VCSELs on Ge or GaAs substrate thicknesses and epitaxy process conditions. It was found that adju…
