Abstract:
An optical regenerator comprising:a first path for processing a demultiplexed optical channel signal of an optical input signal comprising N wavelength division multiplexed channel signals received by the regenerator, the first path comprising: clock recovery means responsive to the demultiplexed optical channel signal for generating an electrical clock signal having a frequency corresponding to a bit rate frequency of the demultiplexed optical channel signal, the electrical clock signal being used to generate at least one electrical driving voltage signal; and an optical modulator comprising at least three electrodes and first and second Lithium niobate optical waveguides interspersed between the at least three electrodes, the optical modulator being responsive to both the demultiplexed optical channel signal and the at least one electrical driving voltage signal from the clock recovery means for generating a regenerated optical output channel signal which is polarization independent.
