“…Fig. 11 shows the BER as a function of the SNR in four cases: (1) No impairments (no PN and unlimited DAC/ADC resolution); (2) With only limited DAC/ADC resolution and no PN; (3) With PN of 200 kHz and no limited DAC/ADC resolution; (4) With both impairments. Note that, the number of bits of the DAC and ADC are set to 6 and 5 bits, respectively [21][22].…”

“…Based on the aforementioned assumptions 1 , the received signal at the output of the analysis filter bank (AFB), at the subcarrier m 0 and the multicarrier symbol l 0 can be expressed as 1 It is important to note that these hypotheses are made to ease the receiver stage processing. In practice, they are not mandatory to allow a functional chain.…”

“…appeared as a promising multicarrier modulation candidate in optical fiber communication systems [1][2][3][4]. Compared to the commonly used optical orthogonal frequency-division multiplexing (OFDM) modulation, FBMC/OQAM has no cyclic prefix and hence increases the throughput rate.…”

Filterbank multicarrier based on offset-quadrature amplitude modulation (FBMC/OQAM) is a promising candidate for optical fiber communication systems, thanks to its better time/frequency confinement compared to other multicarrier modulations. Among linear impairments, the compensation of fiber-induced chromatic dispersion (CD) and laser-induced phase noise (PN) in FBMC/OQAM systems induces a compromise in terms of the number of used subcarriers. Considering a fixed dedicated signal bandwidth, the number of subcarriers is expected to be large enough to allow a better frequency-domain CD compensation. On the other hand, it should be sufficiently small in order for the compensation of common phase error inherent to the PN to work properly. In this paper, we experimentally demonstrate the trade-off between CD and PN compensation that we previously highlighted by simulations. More specifically, considering a 20-GHz FBMC/4− −OQAM modulation and an aggregated laser linewidth of about 200 kHz, we show that the maximum transmission distance reaches 3100 km with nearly 512 active subcarriers and 3-tap equalizers, when a maximum 1-dB optical signal-to-noise ratio (OSNR) penalty at a bit-error-rate (BER) of 3.8× ×10 -3 can be tolerated. Moreover, we propose and validate a frame structure and an integrated synchronization/channel equalization architecture to implement a standalone demodulation system.

Tailored complex optical fields, may find applications in optical manipulation, imaging, microscopy, quantum information processing, and optical communications. Here, we focus on data information transfer for optical communications using complex optical fields. We review recent research progress in complex optical field modulation, multiplexing, and multicasting for data information transfer on different platforms of waveguides, free space, and fiber. Challenges and perspectives are also discussed.

“…Several solutions for PN compensation have been proposed so far. An innovative phase tracking algorithm is designed in [2] to minimize the error at the output of the equalizer. A modified feedforward blind phase search algorithm (M-BPS) is introduced in [1] and its reduced complexity versions are presented in [3][4].…”
