In the present era of technology, it is quite fascinating to design a system capable of
transmitting information from one end to another by using the optical spectrum. This system …

Optical wireless communication (OWC) links enable high-speed data transmission between
earth stations and satellites. The propagation of optical signals through the atmosphere …

Energy consumption has become one of the most challenging problems in future wireless
communication networks. One of the promising methods in fifth generation (5G) cellular …

We propose a single laser source-based free space optical link for transmission of
bidirectional data of three different channels between modular data centers, where each …

Relay nodes that are proposed for extending the length of free space optical links are
generally based upon simple optical amplifiers. In this article, we have proposed an all …

Reconfigurable intelligent surface (RIS) technology is regarded as one of the important
technologies for future 6G mobile communication networks. However, RIS can only …

In this work, we investigate the performance of dual-hop hybrid free-space optical/radio
frequency (FSO/RF) systems with decode-and-forward relaying, where the FSO link …

We propose and demonstrate a generalized framework for performance limit evaluation and
comparison of multihop optical repeated and regenerated links. The model developed is …

The escalating demand for bandwidth-intensive applications in next-generation
communication systems, driven by the proliferation of IoT and multimedia applications …

In this paper, an electroabsorption modulator-based relay is employed for the transmission
of on-off keying (OOK) and differential phase shift keying (DPSK) signals over a free space …
