Abstract
Provided are a method for processing optical signals and a transmitter for the signals adapted for an ultra-high bit rate. The method uses an optical pulse stream with a carrier suppressed return to zero (CS-RZ) format to be obtained from an optical modulator that is driven using a combination of two sinusoidal electrical voltages, one at a frequency f and the other at the third harmonic 3f of the frequency f.
