Title: The Innovative Mind of Lihong Tang: Pioneering Wavelength Selective Switch Technology

Introduction: Lihong Tang, an accomplished inventor based in Wuhan, China, has made significant contributions to the field of optical technologies. With a total of three patents under his name, Tang is recognized for his innovative designs and engineering solutions aimed at enhancing wavelength selective switch functionalities.

Latest Patents: Among his latest innovations are two remarkable patents concerning wavelength selective switches. The first patent describes a wavelength selective switch that features an attenuation liquid crystal cell array paired with a switching liquid crystal cell array. This design is engineered to allow light to pass through specific regions, with a first ECB liquid crystal cell array incorporating multiple pixel units. Each pixel's phase can be adjusted via different voltage settings, leading to the creation of a phase pattern that exhibits lens properties. By altering the center of the lens formed by this pattern, Tang's invention efficiently selects an outgoing port for the transmitted light.

The second patent elaborates on a new type of liquid crystal (LC)-based attenuation switching device. This device integrates an LC switching module designed to redirect an incoming beam to one of several output paths. The LC switching module comprises one or more switching cells, along with a mirror to reflect the light beam after switching, ensuring that it is outputted through the correct port. Additionally, Tang's design includes a temperature compensation module that adjusts the curvature of the mirror in response to temperature changes, thereby addressing the potential deformation in the LC switching cells.
