Latest Patents

Qian Cui holds a patent for a "Method for implementing folding MxN wavelength selective switch." This invention provides a novel method for implementing a folding M×N wavelength selective switch using a combination of optical elements. The design incorporates a one-dimensional single-mode fiber optic collimator array, a short-focus cylindrical mirror, a first long-focus cylindrical mirror, a retroreflector, a transmission phase diffraction grating, a second long-focus cylindrical mirror, a liquid crystal spatial light modulator, and a liquid crystal graphic loading control system. The ingenious folding structure allows the same set of optical elements to be used for both incident and outgoing light, thereby reducing space and improving port utilization. The working area of the liquid crystal spatial light modulator is doubled, significantly increasing the number of accommodating ports. This innovative design greatly enhances the quantity of M×N ports of the WSS.
