All-optical amplify-and-forward relaying system for atmospheric channels
Aminikashani, Mohammadreza; Rad, M. M.; Safari, M.; Uysal, Murat (IEEE, 2012-10)In this letter, we investigate the performance of a dual-hop free space optical link with an all-optical amplify-and-forward relay. We employ photon counting methodology and derive closed form expressions for the end-to-end ... -

Multi-hop quantum key distribution with passive relays over underwater turbulence channels
Raouf, Amir Hossein Fahim; Safari, M.; Uysal, Murat (IEEE, 2020)Absorption, scattering, and turbulence experienced in underwater channels severely limit the range of quantum communications. In this paper, to overcome range limitations, we investigate a multi-hop underwater quantum key ... -
Multi-hop quantum key distribution with passive relays over underwater turbulence channels
Raouf, Amir Hossein Fahim; Safari, M.; Uysal, Murat (The Optical Society, 2020-12-01)Absorption, scattering, and turbulence experienced in underwater channels severely limit the range of quantum communication links. In this paper, as a potential solution to overcome range limitations, we investigate a ... -
Multi-hop relaying over the atmospheric poisson channel
Safari, M.; Rad, M. M.; Uysal, Murat (IEEE, 2011)In this paper, we study the outage behavior of a decode-and-forward multi-hop free-space optical (FSO) system over a Poisson channel degraded by atmospheric turbulence. We assume that perfect channel side information (CSI) ... -
Multi-hop relaying over the atmospheric poisson channel: outage analysis and optimization
Safari, M.; Rad, M. M.; Uysal, Murat (IEEE, 2012-03)In this paper, we study the outage behavior of a decode-and-forward multi-hop free-space optical (FSO) system over a Poisson channel degraded by atmospheric turbulence. We assume that perfect channel side information (CSI) ... -
Optimal relay placement and diversity analysis of relay-assisted free-space optical communication systems
Kashani, M. A.; Safari, M.; Uysal, Murat (IEEE, 2013-01)Relay-assisted free-space optical (FSO) transmission exploits the fact that atmospheric turbulence fading variance is distance dependent and yields significant performance gains by taking advantage of the resulting shorter ... -
Optimal relay placement in cooperative free-space optical communication systems
Aminikashani, Mohammadreza; Safari, M.; Uysal, Murat (IEEE, 2012)Relay-assisted free-space optical (FSO) transmission exploits the fact that atmospheric turbulence fading variance is distance dependent and yields significant performance gains by taking advantage of the resulting shorter ... -
Performance analysis of decoy state quantum key distribution over underwater turbulence channels
Raouf, Amir Hossein Fahim; Safari, M.; Uysal, Murat (Optica Publishing Group, 2022-06-01)Decoy state quantum key distribution protocols have been studied for atmospheric, fiber, and satellite links; however, those results are not directly applicable to underwater environments with different channel characteristics. ... -
Performance analysis of quantum key distribution in underwater turbulence channels
Raouf, Amir Hossein Fahim; Safari, M.; Uysal, Murat (The Optical Society, 2020)The current literature on quantum key distribution is limited mainly to transmissions over fiber optic, atmospheric, or satellite links and is not directly applicable to underwater environments with different channel ... -
Vehicular visible light communications with SPAD receivers
Karbalayghareh, Mehdi; Miramirkhani, Farshad; Safari, M.; Uysal, Murat (IEEE, 2019)Light emitting diodes (LEDs) are increasingly used in automotive exterior lighting. The expected wide availability of LED-based front and back lights makes visible light communication (VLC) a natural vehicular connectivity ...
