Enabling WiGig Communications Using Quantum-Dash Laser Source Under Smoky Weather Conditions

Abstract

Wireless Gigabit (WiGig) is a recent wireless local area network that operates at the 60-GHz band and supports a transmission data rate of up to 20 Gbps. This paper demonstrates the generation of a V-band millimeter-wave (mmWave) signal using a new class of InAs/InP quantum-dash laser-based comb source operating in the L-band region. A 62.5-GHz mmWave signal is generated with electrical linewidth and phase noise characterization of 1 kHz and −65 dBc/Hz, respectively. Then, the transmission of the 6-Gbaud quadrature phase-shift keying (12 Gbps) signal is experimentally achieved over a hybrid radio-over-fiber (RoF) and radio-over-free-space (RoFSO) architecture comprising an 11.6-km single-mode fiber (SMF), 6-m FSO, and up to 2-m wireless link. Moreover, we also report this WiGig signal's transmission performance in terms of the measured bit error rate and error vector magnitude under various density smoke FSO channels, exhibiting a visibility range of ∼100 m for error-free transmission.

Research Progress of High-Speed Data Transmission Technology for Lightweight and Small-Sized Unmanned Aerial Vehicle Platforms

“…The results show that a maximum data rate of 792.64 Tbps was achieved using one-channel dense wavelength division multiplexing, and the maximum transmission distance was extended to 1600 km with a BER of 10 −12 . Ragheb AmrM et al from King Saud University successfully realized the transmission of a 6 Gbaud orthogonal phase shift keying signal by fusing RoF and RoF-FSO and measured the relationship between the BER and error vector magnitude of the signal under different densities of smoke FSO channels [23]. The results show that the visibility range can reach one hundred meters under error-free transmission.…”

Globalization in Photonics Research and Development

“…The TIC-RFTONICS in KSU produces both wireless and lightwave prototypes, while delivering significant research findings in both RF and optical wireless communications. [43], [44], [88]- [90] Through the TIC-RFTONICS, the collaboration among Saudi Arabia's universities were further fostered across KSU-KFUPM-KAUST [91], [92] in collaboration with other prominent communication scientist, such as Professor Mohamed-Slim Alouini [93] [https://cemse.kaust.edu.sa/ctl].…”
