Performance Optimization of SNR and SFDR in RoF Link for the Next Generation Networks

The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.
Figure 1 showing the fundamental concept of RoF link designing over a dispersive medium. The complete RoF link is divided into three different sections. These sections are nominated as, central station (CS), optical distribution networks (ODN) and base station (BS). CS to BS conversation is called downlink transmission, while from BS to CS it is called

Using a $\hbox{Si}_{3}\hbox{N}_{4}$ Ring Resonator Notch Filter for Optical Carrier Reduction and Modulation Depth Enhancement in Radio-Over-Fiber Links

IEEE Photonics Journal, 2013
Optical carrier reduction via the use of a Si3N4 ring resonator notch filter (RRNF) is proposed and experimentally demonstrated as a means for improving the modulation efficiency in 10-GHz radio-over-fiber (RoF) links.

Frequency Comb Effect on Chaos in Semiconductor Lasers, a Bifurcation Study

International Journal of Optics, Volume 2025, Issue 1, 2025.
This study investigates the effects of optical frequency comb injection on the chaotic dynamics of semiconductor lasers through a bifurcation analysis. By examining the behavior of semiconductor lasers under different comb parameters (i.e., the number of signals, comb spacing), the research explores how these factors influence the system’s transition ...
