“…However, the free-space transmission rate of 84 Gb/s (downstream)/45 Gb/s (upstream) and the free-space transmission distance of 200 m are considerably lower than those of 448 Gb/s and 600 m adopted in this demonstrated FSO communication. Aboagye et al achieved a 112 Gb/s/channel × 4-channel (448 Gb/s) wavelength-division-multiplexing (WDM) polarization-division-multiplexed (PDM)-differential quadrature phase shift keying (DQPSK) lightwave transmission system [16]. Its total transmission capacity of 448 Gb/s is equal to that of our proposed FSO communication.…”

A 448-Gb/s four-level pulse amplitude modulation (PAM4) free-space optical (FSO) communication through 600 m free-space link was constructed, utilizing polarization-multiplexing injection-locked vertical-cavity surface-emitting lasers (VCSELs) for presentation. When uniting fourwavelength polarization-multiplexing and PAM4 modulation schemes, the transmission capacity of FSO communications is substantially multiplied, with an aggregate transmission rate of 448 Gb/s [56 Gb/s PAM4/wavelength × 4 wavelengths × 2 polarizations (x-and y-polarizations)]. The results show that four 1.55 µm VCSEL transmitters with injection locking technique are sufficiently powerful for 448 Gb/s PAM4 signal transmission. Adopting a tunable optical band-pass filter and a polarization beam splitter for wavelength filtering and polarization de-multiplexing, the polarized wavelengths are effectually filtered and de-multiplexed in each polarized state. As the polarization state is well preserved in the scenario over 600 m free-space transmission, a sophisticated polarization tracker is not required in this proposed FSO communication. High bit error rate performance and accepted PAM4 eye diagrams are attained through 600 m free-space transmission. The four-wavelength polarization-multiplexing PAM4 FSO communication established here reveals the prominent benefits of high aggregate transmission capacity and long-distance free-space link.

“…It will be somewhat difficult to track the polarization state with disturbed water as well. However, a polarization tracker can be installed to transfer the arbitrary polarization to the settled polarization state [27], [28]. The polarization tracker recovers two orthogonal polarization states to mitigate the polarization state with long-distance underwater link/disturbed water.…”

A 500-Gb/s four-level pulse amplitude modulation (PAM4) free-space optical (FSO)underwater wireless laser transmission (UWOC) convergent system over 100 m free-space transmission with either 10 m piped underwater link or 5 m turbid underwater link is established, employing a red/green/blue (R/G/B) five-wavelength polarization-multiplexing scheme as a demonstration for the first time. Integrating PAM4 modulation with five-wavelength polarization-multiplexing scheme, the channel capacity of FSO-UWOC convergent systems is significantly increased with an aggregate data rate of 500 Gb/s [50 Gb/s PAM4/wavelength × 5 wavelengths × 2 polarizations (p-and s-polarizations)]. Results reveal that five R/G/B laser diode (LD) transmitters with two-stage light injection and optoelectronic feedback techniques are capably adopted for 500 Gb/s PAM4 signal transmission. Compared with prior FSO-UWOC convergence and visible light communication using polarization-multiplexing R/G/B LDs, it shows a prominent one with the benefits of high aggregate transmission rate and long-range optical wireless link. Excellent bit error rate performance and accepted PAM4 eye diagrams are attained over a 110-m/105-m FSO-UWOC link. This demonstrated five-wavelength polarization-multiplexing FSO-UWOC convergent system is promising because it not only integrates free-space backbone with underwater optical wireless feeder, but it also substantially multiplies total channel capacity.
