“…Additionally, for the LG[0,2] mode shown in Figure 6b, faithful transmission ranges of 26 m under weak, 20 m under moderate, and 18 m under strong scintillation effects are obtained for all types of water. According to Figure 6c, weak, moderate, and strong scintillation effects offer wireless ranges of 22-24 m, 16-18 m, and 13-15 m, respectively, at LG [0,4]. Figure 6d shows that, for the LG[0,8] mode, the weak, moderate, and strong scintillation effects achieve maximum ranges of 15-23 m, 13-15 m, and 12-14 m, respectively.…”

“…In recent years, wavelength division multiplexing (WDM) and OAM have been integrated using multi-mode fibers (MMFs) with a range of 1000 m and a 10 Gbps throughput [4]. In [8], the WDM and OAM techniques were integrated at a 1.6 Tbps data rate.…”

“…The mode division multiplexing (MDM) method can be utilized to upgrade the capacity of an OWC link that uses spatial light modes as the information carrier. The orbital angular momentum (OAM) mode has been widely used to improve the capacity of OWC links incorporating the spatial orthogonality of distinct OAM modes [4]. Due to its distinguishability as well as orthogonality through distinct limitless charge numbers, OAM acts as an auxiliary degree of freedom in support of de-/multiplexing and for enhancing overall system capacity [5].…”

With their unique capability to deal with a considerable geographic area, satellite–ground–underwater optical wireless communication (OWC) systems are an appealing alternative to meet the ever-increasing demand for end-to-end broadband services. Using four different Laguerre–Gaussian (LG) modes, an orbital angular momentum (OAM) multiplexing method was developed to enhance the spectral efficiency and system capacity of the satellite–ground–underwater OWC system. At an aggregate throughput of 160 Gbps, LG[0,0], LG[0,2], LG[0,4], and LG[0,8] were realized. Various atmospheric conditions, water types, and scintillation effects were used to evaluate the performance of two separate OWC links for satellite-to-ground and ground-to-underwater communication. A maximum OWC range of 21,500–30,000 km has been obtained under weak-to-strong turbulence for satellite-to-ground scenarios, and a range of 12–27 m underwater for ground-to-underwater scenarios under various scintillation effects. At LG[0,0], in pure sea, the maximum gain is −75.02 dB, the noise figure is 75.02 dB, the output signal is −78.32 dBm, and the signal-to-noise ratio is 21.67 dB. In comparison with other works in the literature, this system shows a superior performance.

Vortex beams carrying orbital angular momentum (OAM) provide a new degree of freedom for light waves in addition to the traditional degrees of freedom, such as intensity, phase, frequency, time, and polarization. Due to the theoretically unlimited orthogonal states, the physical dimension of OAM is capable of addressing the problem of low information capacity. With the advancement of the OAM optical communication technology, OAM router devices (OAM-RDs) have played a key role in significantly improving the flexibility and practicability of communication systems. In this review, major breakthroughs in the OAM-RDs are summarized, and the latest technological standing is examined. Additionally, a detailed account of the recent works published on techniques related to the OAM-RDs has been categorized into five areas: channel multicasting, channel switching, channel filtering, channel hopping, and channel adding/extracting. Meanwhile, the principles, research methods, advantages, and disadvantages are discussed and summarized in depth while analyzing the future development trends and prospects of the OAM-RDs.
