Title: Hong Min and His Optical Attenuator Invention.

Introduction

Hong Min is an inventor based in Wuhan, China, associated with Huawei Technologies Co., Limited. His listed patent concerns a variable optical attenuator that uses a switchable polarization grating to control light.

Latest Patents

The provided information lists one patent for Hong Min: “Variable Optical Attenuator Comprising a Switchable Polarization Grating.” The invention describes an optical system containing a collimator, a switchable polarization grating, a reflector, and a voltage controller. The collimator directs incoming light to the grating, which diffracts it toward the reflector. After reflection, the light passes through the grating again and is diffracted before returning to the collimator. The voltage controller adjusts the voltage across the liquid-crystal layer’s electrodes, enabling control of the grating’s operation. Hong Min is credited with 1 patent in the information provided.

Career Highlights

Hong Min’s listed patent connects his inventive work with optical technologies at Huawei Technologies Co., Limited. The patent focuses on controlling light transmission through a switchable polarization grating and a voltage-adjustable liquid-crystal layer.
