20250180897. Hybrid Modulation (SHANGHAI JIAOTONG UNIVERSITY)
HYBRID MODULATION METHOD AND SYSTEM
Abstract: a hybrid modulation method and system is provided. the method includes the following steps: establishing a simulation model of a spatial light modulator; obtaining, by the simulation model, a phase modulation depth of a phase modulation performed by a blazed grating at each communication port, where within a phase modulation range, when light output from a zerocommunication port is diffracted into a ktarget communication port, the simulation model obtains diffraction efficiencies of various orders at different phase modulation depths, a phase modulation depth a� corresponding to a highest isolation is selected as a phase modulation depth of the kcommunication port, where k∈(0, k); and performing a phase modulation depth a� on light that is output from the zerocommunication port of a communication fiber and that is to be diffracted into the ktarget communication port.
