Abstract
We propose an optical PSK modulation scheme achieved by direct modulation of a laser diode with a wide flat FM response. We call it Direct-Modulation PSK (DM-PSK). We performed 4-Gb/s DM-PSK and CP-FSK transmission experiments at 135 un over 233 km of conventional 13-. un zero-dispersion fiber. The receiver sensitivity degradation due to chromatic dispersion was 0. 7 dB for DM-PSK smaller than that of 2. 5 dB for CP-FSK.
