Latest Patents

Zuoxi Li holds a patent for a waveguide-integrated avalanche photodiode. This invention describes various embodiments of a monolithic avalanche photodiode (APD) that can be fabricated on a silicon-on-insulator substrate. The monolithic APD features an optical waveguide that effectively guides incident light to the active region of the device. An optical coupler is integrally formed with the optical waveguide to capture the incoming light. Additionally, the design includes an optical reflector that reflects a portion of the incident light back to the optical coupler for further capturing. The active region of the APD comprises an absorption layer that converts the incident light into a photocurrent, an epitaxial structure that amplifies the photocurrent through avalanche multiplication, and a pair of electrical conductors for conducting the amplified photocurrent. This innovative approach enhances the efficiency and performance of photonic devices.
