Orbital angular momentum (OAM) mode multiplexing is achieving utmost interest for the
enhancement of transmission capacity and spectral efficiency. We have reported a (2× 8× …

The demand for large bandwidth and high data rates in communication systems has
become the main cause of the upgrade of traditional networks into free space optical (FSO) …

The efficiency and reliability of radio over free space optical communication may be
significantly degraded by different weather conditions, thus leading to decrease and …

Advancement in the technology and optical communication sector has led to an increase in
the demands of high bit rate and bandwidth, required for reliable data transmission. To meet …

The twisted light beams carry orbital angular momentum (OAM), which acts as additional
degrees of freedom. In this work, we have proposed a free space optics (FSO) …

The present study focuses on analysing the bit error rate (BER) of single-input single-output
and multiple-input multiple-output Radio-over free space optics system under atmospheric …

Abstract Free Space Optics (FSO) is one the most in-demand technology, and is used
indoors, on the ground, in space, and even underwater. It is used to broaden communication …

In this work, a radio over free-space optical communication (Ro-FSO) link has been
examined considering quadrature amplitude modulation (64-QAM) based orthogonal …

In this study, a new four channel de-multiplexer with a ring resonator design is proposed.
The bus waveguide and drop waveguide that make up the Ring Resonator are ring-shaped …

This paper successfully demonstrated simulated analysis and investigation of 100
multichannel DWDM-based FSO system having each channel data rate 10 GB/s separated …
