Latest Patents

Tzung I Su holds a patent for a "High performance GeSi avalanche photodiode operating beyond Ge bandgap limits." This invention describes avalanche photodiodes that incorporate at least one top stressor layer on a germanium (Ge) absorption layer. The top stressor layer enhances the tensile strain of the Ge absorption layer, allowing the APDs to operate at longer wavelengths beyond 1550 nm. The patent details a four-layer structure for the top stressor layer, which includes an amorphous silicon (Si) layer, a first silicon dioxide (SiO) layer, a silicon nitride (SiN) layer, and a second SiO layer. Additionally, the Ge absorption layer can be doped with p-type dopants to create a graded doping profile, which helps reduce dark currents in the APDs.
