Optical generation of 43 Gbit/s phase-shaped binary transmission format from DPSK signal using 50 GHz periodic optical filter

A novel method to optically generate PSBT format at 43 Gbit/s is proposed hereafter. Performance have been compared with NRZ format showing reduced OSNR penalty by 0.7 and 1.3 dB for 4.10-3 (FEC limit) and 10-5 BER, respectively. (2 pages)
