zum Thema:

„Photonic Device Applications of Ge Layers Epitaxially Grown on Si”

Abstract

Our recent progresses are presented on waveguide-integrated vertical pin PDs of Ge layers epitaxially grown on Si-on-insulator wafers by chemical vapor deposition from the viewpoint of near-infrared optical communications. Ge PDs reveal high responsivity of ~1 A/W at 1.55 µm, high operation frequency of 30 GHz, and low leakage current below 0.1 uA. Strain engineering to control the operation wavelength of Ge photonic devices is also presented as well as n-type doped Ge toward light emitters.
