International Journal of Optics, Volume 2025, Issue 1, 2025.This paper proposes a novel phase‐tunable mixer based on a cascaded dual‐drive Mach–Zehnder modulator (DDMZM), designed to address the critical need for simultaneous frequency mixing and precise phase control in phased array antennas. Unlike conventional mixers, the proposed structure uniquely combines frequency mixing and phase tuning, enabling ...

An Elastic Optical Network-based Architecture for the 5G Fronthaul
Anais do XXXVI Simpósio Brasileiro de Redes de Computadores e Sistemas Distribuídos (SBRC 2018), 2018 In 5G networks, the traffic demands are expected to increase significantly. To deal with this problem, many research efforts focus on TWDMPON for the fronthaul. However, TWDM-PON suffers from the issue of wasted bandwidth when a demand is smaller than the channel.
