Latest Patents

One of Yu Sun's latest patents is focused on spatial division multiplexed optical communication systems and amplifiers. This patent describes an optical amplifier assembly designed for spatial division multiplexing (SDM) optical communication systems. The assembly includes a single pump assembly that amplifies signals traveling on separate fiber paths in different directions. Each fiber path consists of multiple spatial dimensions, and the pump assembly features several pump sources to ensure redundancy. Additionally, the optical amplifier assembly incorporates splitters to distribute outputs from the pump sources to amplifiers linked to various spatial dimensions. This innovative design allows for different modulation formats to be utilized across the spatial dimensions, with varying pump power allocated to each format. Furthermore, amplifiers with complementary outputs can be connected to balance out gain deviations.

Another notable patent by Yu Sun is a system and method for blind equalization and carrier phase recovery in a quadrature amplitude modulated (QAM) system. This invention provides a method for blind equalization of a QAM signal using an algorithm characterized by a cost function based on the Euclidean distance between points in the constellation associated with the QAM signal. This approach enhances the accuracy of signal processing in communication systems.
