Abstract
Official abstract text for this publication.
In an optical transmission system using an RZ code, in order to improve the quality of the modulated transmission signal, an RZ optical modulator includes an RZ carver that outputs a optical pulse train of the RZ code, a polarization adjustment device which improves and outputs a polarization extinction ratio of optical pulse train outputted from the RZ carver and an optical modulator which modulates and outputs the optical pulse train outputted from a polarization adjustment device.
First claim
Opening claim text (preview).
The invention claimed is: 1. An RZ (return to zero) optical modulator, comprising: an RZ carver that outputs an optical pulse train of an RZ code; a polarization adjustment unit that improves a polarization extinction ratio of the optical pulse train outputted from the RZ carver and outputs the optical pulse train whose extinction ratio is improved; an optical modulation unit that modulates the optical pulse train outputted from the polarization adjustment unit and outputs the…
