Impact of RZ Pulse Carver Phase Errors on Optical DQPSK

Not Accessible

Your library or personal account may give you access

Abstract

The impact of phase errors caused by imperfect return-to-zero (RZ) pulse carving on optical differential quadrature phase-shift keying (DQPSK) is analyzed. The two-symbol-delayed interferometric demodulation is proposed as an effective means to mitigate this degradation.
