A method for modulating an optical signal includes the following steps: modulating the intensity of the optical signal with a nonreturn-to-zero bit signal, and modulating the phase of the optical signal with a periodic phase-shift signal creating an alternating &#x3c0;-phase shift every second, third or more consecutive bit. An optical transmitter for performing the above method comprises a first modulator () modulating the intensity of the optical signal with a nonreturn-to-zero bit signal, and a second modulator () modulating the phase of the optical signal with a periodic phase-shift signal creating an alternating &#x3c0;-phase shift every second, third or more consecutive bit.
