Title: The Innovations of Qi Deng

Introduction

Qi Deng is a prominent inventor based in Cupertino, California, known for his significant contributions to optical technology. With a total of eight patents to his name, he has made remarkable advancements in the field of fiber optics and optical components.

Latest Patents

Among his latest patents, Qi Deng has developed a "Circulator and Polarization Beam Combiner." This system and technique aim to reduce the polarization dependency of optical components by combining the actions of a circulator and a polarization beam combiner. The invention allows for the separation of an optical signal into multiple orthogonally oriented polarization components, rotating at least one of the components to ensure parallel polarization orientation. The components are then propagated through respective input ports of an optical component simultaneously, with the output components being recombined into an output optical signal.

Another notable patent is the "Single-Fiber Bi-Directional Transceiver." This integrated transceiver facilitates bi-directional communication along a single fiber-optic cable within a fiber-optic network. The transceiver comprises an active part for both transmit and receive functions, which includes a photo diode and a laser diode attached to a substrate. Bi-directional communication is achieved through the use of an optical circulator, which is also connected to the substrate and limits back reflections into the active part of the transceiver.
