Realistic modeling of Photonic Terahertz Communication based on a real-world 30 km 30 Gbps experimental demonstration
Mingxu Wang, Jianjun Yu, Xianming Zhao +9
Experimental studies have demonstrated that THz links can support multi-kilometer, gigabit-per-second wireless transmission. However, few studies have effectively validated channel…
Analytical Channel Modeling and Stability Aware Optimization of Optical Inter Satellite Links
Hossein Safi, Ziheng Wang, Stijn Mast +2
Optical inter-satellite links (OISLs) are key enablers for high-capacity space networks and next-generation satellite constellations. However, their extreme directionality makes li…
OHL-Assisted All-Optical Regenerative Relaying for Pointing-Impaired M-PAM Inter-Satellite Links
Meysam Ghanbari, Mohammad Taghi Dabiri, Zain Ali +4
Rapid inter-satellite traffic growth in LEO constellations demands spectrally efficient, low-latency optical relaying. While amplify and forward (AF) relays are latency-efficient,…
Diffractive optical element for super-Gaussian beam shaping on intersatellite optical communications
Mario Badás Aldecocea, Ziheng Wang, Mohammad Dabiri +1
Pointing jitter can significantly degrade the performance of intersatellite optical communication links. This work investigates diffractive optical beam shaping as a means of gener…
VCSEL-Enhanced Holographic Communication for Next-Generation LiFi: State-of-the-Art, Applications, and Future Directions
Hossein Safi, Iman Tavakkolnia, Harald Haas
Light Fidelity (LiFi) has emerged as a promising wireless technology that exploits the vast unlicensed optical spectrum to complement radio frequency networks. Recent advances in l…
Q-Learning for 3D Coverage in VCSEL-based Optical Wireless Systems
Hossein Safi, Rizwana Ahmad, Iman Tavakkolnia +1
Beam divergence control is a key factor in maintaining reliable coverage in indoor optical wireless communication (OWC) systems as receiver height varies.Conventional systems emplo…
Ethernet-over-OWC Using VCSELs: Transparent Gigabit Links with Low Latency and Robust Alignment Tolerance
Hossein Safi, Isaac N. O. Osahon, Iman Tavakkolnia +1
We demonstrate a fully bidirectional 1 Gbs Ethernet over OWC link over a 1m free space path using a VCSEL-PIN pair and only commercially available components. The unamplified, tran…
Modulating Retroreflectors for CubeSat Optical Inter Satellite Links: Modeling, Optimization, and Benchmarking
Makafui Avevor, Hossein Safi, Harald Haas +1
Modulating retroreflectors (MRRs) offer a promising pathway to low-complexity and energy efficient asymmetric optical inter-satellite link (OISL) for small spacecrafts, such as Cub…
