Optische Modulationsart für NRZ-Signale und optischer Sender

摘要

An optical modulation scheme for transmitting data over a fiber optic transmission line is proposed where the following steps are realized: Creating a NRZ signal by amplitude modulation Modulating two branches of a interferometer structure by complementary electrical signals Shifting one of the electrical signals against the other electrical signal in time. Further an optical transmitter is proposed which can modulate the light in the new proposed modulation scheme.
