Title: Dezhong Yu: Innovator in Optical Signal Processing
Introduction
Dezhong Yu is a prominent inventor based in Shenzhen, China. He has made significant contributions to the field of optical signal processing, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is a "Dynamic dispersion detecting method and apparatus." This invention includes a tunable dispersion compensation module, a demodulator, a receiver, a partial band radio frequency power detecting unit, and an electrical signal ratio calculating unit. The method involves demodulating a phase of a received optical signal, converting it into an electrical signal, and sampling the radio frequency power to obtain a radio frequency signal. The process allows for tuning a dispersion compensation value to find a peak electrical signal ratio, ultimately determining the residual dispersion value of a system.
Another notable patent is the "Method and device for generating optical signals." This method involves receiving a first Non Return to Zero (NRZ) data signal and a synchronous clock signal, performing Return to Zero (RZ) processing to generate a first complementary RZ data signal pair, and modulating these signals on light to create an RZ-Differential Quadrature Phase Shift Keying (RZ-DQPSK) optical signal. This innovation reduces costs and insertion loss while lowering the requirements for input optical power.
