Optical and mobile broadband services have been widely adopted to support various applications including center-to-end and end-to-end communications. This raises further expectations for more and more natural and realistic communications by increasing network bandwidth and reducing latency. To support this evolution, 6G mobile is intended to increase the bandwidth to much over 10 Gbit/s and reducing the end-to-end latency to less than 1 ms. However, electrical processing is the key bottleneck to drastically increasing the bandwidth and reducing the latency in the current network architecture especially when the explosion of power consumption needs to be avoided. This paper discusses future optical network architectures and technologies to resolve the issue. In particular, it focuses on photonic networking to minimize the electrical processing across metro and access sections, and describes the technical challenges.

“…The major variations in 6G network realization are the deployment of fiber to the antenna section using supercontinuum enabled PCF with high birefringence. Further, the key 6G enablers of optical technologies for mobile transport network include, reconfigurable Mach Zehnder Modulators, and optical dispersion compensator (P. Iovanna, et al., 2021). These devices enable the deployment of optical hub over optical distribution fibers for 100 Gb/s in the downstream.…”

The Sixth Generation (6G) networks have identified the use of frequency range between 95 GHz and 3 THz with a targeted data rate of 1 Terabytes/second at the access network for holographic video applications. As is demands broadening of spectrum at the core network, this paper proposes a Supercontinuum Generation (SCG) through photonic crystal fiber (PCF) as it provides excellent broadening of the optical spectrum. Discussed in the paper is supercontinuum generation at high pumping power as per the standards specified by the International Telecommunications Union (ITU). The proposed PCF is designed with silicon nanocrystal core and the cladding microstructures is arranged in a fusion approach to effectively optimize the optical parameters such as dispersion, nonlinearity, birefringence, group velocity dispersion, and confinement loss. The fused cladding comprises of a flower‐cladding assembly in which air‐holes arrangement is inspired from petals in a pleated structure. Such arrangement is shown here to provide high nonlinearity and negative dispersion for high power supercontinuum generation. The novel nanocore assembly with improved structural constraints delivers a non‐linearity of 6.37×106 W‐1km‐1 and a negative dispersion of ‐142.1 (ps/nm‐km) at 1550 nm. Moreover, a supercontinuum spectrum is generated using different pulse widths ranging from 350 ps to 650 ps with 25kW pump power for PCF lengths of 10 mm and 15 mm.This article is protected by copyright.
