“…We considered LG mode profiles with larger differences such as LG00, LG140, and LG400 to realize OAM multiplexing, and it was observed that mode coupling becomes insignificant in these distant mode profiles as compared to the reported research where LG/HG modes with lesser gaps are considered [ 1 , 43 , 44 , 58 ]. We performed an extensive literature survey and found that the highest capacity that has been reported so far in OSC is 4 [ 44 ], 3.84 [ 61 ], 1.6 Tbps [ 62 ], and 320 Gbps [ 63 ]. Therefore, an ultra-high capacity 4.8 Tbps OSC-OAM system was presented for the first time in this work.…”

“…In this section, the performance of the proposed OAM-OSC system is compared with the different reported OSC systems in terms of data rate, channels, capacity, OSC link length, modulation used, multiplexing employed, and performance, as shown in Table 2 . It is observed that the highest capacity is accomplished in the proposed work as compared to [ 41 , 42 , 44 , 61 , 62 , 63 ]. Moreover, the use of DQPSK [ 41 ], 4-QAM/PSK-OFDM [ 43 ], PDM-QPSK [ 44 ], SP-QAM [ 59 ], PDM-4-QAM [ 37 ], PDM-16-QAM [ 58 ], PDM-64-QAM [ 59 ], and PDM-128-QAM [ 62 ] have been reported in these researches.…”

Twisted light beams such as optical angular momentum (OAM) with numerous possible orthogonal states have drawn the prodigious contemplation of researchers. OAM multiplexing is a futuristic multi-access technique that has not been scrutinized for optical satellite communication (OSC) systems thus far, and it opens up a new window for ultra-high-capacity systems. This paper presents the 4.8 Tbps (5 wavelengths × 3 OAM beams × 320 Gbps) ultra-high capacity OSC system by incorporating polarization division multiplexed (PDM) 256-Quadrature amplitude modulation (256-QAM) and OAM beams. To realize OAM multiplexing, Laguerre Gaussian (LG) transverse mode profiles such as LG00, LG140, and LG400 were used in the proposed study. The effects of the receiver’s digital signal processing (DSP) module were also investigated, and performance improvement was observed using DSP for its potential to compensate for the effects of dispersion, phase errors, and nonlinear effects using the blind phase search (BPS), Viterbi phase estimation (VPE), and the constant modulus algorithm (CMA). The results revealed that the proposed OAM-OSC system successfully covered the 22,000 km OSC link distance and, out of three OAM beams, fundamental mode LG00 offered excellent performance. Further, a detailed comparison of the proposed system and reported state-of-the-art schemes was performed.

We study scintillation and bit error rate performance of mirrored Bessel beams through turbulent atmosphere in this article. We benefit from numerical method to model the atmosphere. Since scintillation plays a vital role in optical wireless applications, reduction in this term provides better performance in these systems. Bearing in mind this, our results indicate that it is possible to decrease scintillation by increasing beam order to three when strong turbulent conditions are satisfied. In addition, we observe that argument of Bessel beam has more dominant role than beam order in moderate turbulence. Lastly, mirroring brings us a slight advantage in case of bit error rate. Results of this study can be beneficial for optical link designers.

“…Similarly, effect of underwater turbulence is tested via transmitting video (Priyalakshmi and Mahalakshmi 2020). On the other hand, possible data rates can reach up to 3.84 Tbps with distance 58,000 km since there is no turbulence between satellites (Sumathi et al 2020).…”

We present on-axis, aperture averaged scintillation, and bit error rate performance of Mathieu-Gauss beams (MGB). We model atmosphere utilizing random phase screen. Our investigations show that scintillation indexes of both odd and even modes of MGBs are less than Gauss beam. In the comparison of odd and even modes, odd modes draw the attention with its less scintillation index. In case of aperture averaged scintillation, all types of MGBs are advantageous comparing with Gauss beam but this advantage vanishes with increase in receiver aperture opening. Mitigation in scintillation index brings us 10 −6 times lesser bit error rate (BER) than Gauss beam.
