主　　题：optical polarization fiber 

摘      要：Multimode fibers(MMFs)are a promising solution for high-throughput signal transmission in the time ***,crosstalk among different optical modes within the MMF scrambles input information and creates seemingly random speckle patterns at the *** characterize this process,a transmission matrix(TM)can be used to relate input and output *** innovations use TMs to manipulate the output field by shaping the input wavefront for exciting advances in deep-brain imaging,neuron stimulation,quantum networks,and analog ***,these approaches consider input/output segments as independent,limiting their use for separate signal processing,such as logic *** proposed method,which makes input/output segments as interdependent,adjusts the phase of corresponding output fields using phase bias maps superimposed on input *** superposition enables signal logic operations through a 15-m-long *** experiments,a single optical logic gate containing three basic logic functions and cascading multiple logic gates to handle binary operands is *** operations are performed for multi-bit logic operations,and multiple optical logic gates are reconstructed simultaneously in a single logic gate with polarization *** proposed method may open new avenues for long-range logic signal processing and transmission via MMFs.
