Sub-terahertz (sub-THz) waves, operating in the 0.1-1 THz band, offer significant potential for next-generation 6G systems. These systems stand to benefit from photonic technologies that enable terabits-per-second communication with low latency and h

Two structures that can realise optical single sideband modulation without generating both second order upper and lower sidebands are presented. They are based on a dual-parallel Mach Zehnder modulator (DP-MZM) with an optical filter and a dual-polar

In this paper, a bias-free silicon optical single-sideband (OSSB) modulator without 2nd-order sideband is proposed and theoretically investigated. The proposed modulator is based on a dual-drive Mach-Zehnder modulator (DDMZM) and silicon photonics pl

Guard-band optical single-side-band orthogonal frequency-division multiplexing (GB-OSSB-OFDM) is a good solution to achieve long-haul transmission as well as high receiver sensitivity. A low-complexity receiver with ADC undersampling technique is exp

The optical single sideband (OSSB) scheme is a common choice in radio over fiber system for compensating chromatic dispersion (CD) but it suffers from low signal to noise ratio (SNR).We present the novel technique for SNR improvement using unequal si

In this paper we address the limiting effect of power fading (PF) in fiber optic communication links, due to the fiber’s dispersive properties, and suggest a mitigation approach in intensity-modulated radio-over-fiber (RoF) applications. The propos
