Abstract

This paper depicts a modified return-to-zero differential quadrature phase shift keying (RZ-DQPSK) modulation scheme. A simulative analysis has been performed for an optimization of the proposed scheme. The analysis has also been extended for two different types of commercial fibers; standard single-mode fiber (SSMF) and true wave-reduced slope (TW-RS) fiber to report the similar qualitative performance characteristics. For the sake of better understanding of the proposed modified carving signal RZ-DQPSK scheme, optical spectrum and eye pattern plots are also investigated.
