“…Analysis and experiments have shown that these effects are at least 3 dB weaker than comparable OOK transmission due to the lower peak power, the phase modulation, and pulse-sequence correlations [20,22,34]. In summary, numerous experiments [2,6,15,28,39] have demonstrated the value of leveraging the Raman and DPSK technologies to achieve significant capacity and reach improvements compared with non-Raman and OOK solutions. represents the required OSNR to achieve 10 Ϫ3 BER.…”

“…Later parts of this paper measure the TROF traces of NRZ-DPSK signals with and without chromatic dispersion and find the corresponding electric field of E(t). Not able to generate in our measurement, RZ-DPSK signal is the dominant signal format [1][2][3][4][5][6][7]. Figures 1(c) and (d) show the TROF traces of RZ-DPSK signal.…”

Abstract:Time-resolved optical filtering (TROF) measures the spectrogram or sonogram by a fast photodiode followed a tunable narrowband optical filter. For periodic signal and to match the sonogram, numerical TROF algorithm is used to find the original complex electric field or equivalently both the amplitude and phase. For phase-modulated optical signals, the TROF algorithm is initiated using the craters and ridges of the sonogram.

“…However, the advent of erbium-doped fiber amplifiers refocused the interest on direct-detection techniques and, as a consequence, the possibility of using a Mach-Zehnder delay interferometer in conjunction with a dual-photodiode balanced receiver, to demodulate optical DPSK signals, started to attract attention [3]- [5]. In the last years, direct-detection DPSK has regained momentum aiming mainly dense wavelength division multiplexing (DWDM) long-haul transmission applications [6]- [8]. This renewed interest comes from the fact that DPSK outperforms the traditional binary on-off keying (OOK) in such aspects as receiver sensitivity, robustness to transmission impairments, and tolerance to signal power fluctuations [9], [10].…”

Abstract-In-band crosstalk, due to multiple interferers, has been identified as one of the most severe impairments in optical transparent networks, especially in the ones with a large number of nodes and a high wavelength density. Due to its robustness to in-band crosstalk differential phase-shift keying (DPSK) emerges as an attractive modulation scheme to be used in such environments. This paper proposes a rigorous formulation to estimate the performance of direct-detection DPSK receivers using an eigenfunction expansion technique in the time domain. The method takes into account both the in-band crosstalk, due to an arbitrary number of interfering terms, and the amplified spontaneous emission noise and is able to deal with any combination of optical and electrical filter shapes. Using this method the accuracy of an approximation based on the wideband optical filtering assumption was evaluated and shown that the approximation, although not providing reliable results for the error probabilities, can be used with confidence to compute power penalties due to in-band crosstalk. Furthermore, the crosstalk tolerance of DPSK over on-off keying was quantified and shown that this tolerance is reduced when the number of interferers increases.Index Terms-Differential phase-shift keying, eigenvalues and eigenfunctions, in-band crosstalk, optical networking.
