#### Resilience–throughput–power trade-off in future 5G photonic networks

5G New Radio allows operators to use new and wider spectrum and complements Long-Term Evolution networks with higher data rates and lower latency. Supporting such requirements in the transport network is not only a technological challenge, but a financial one as well. The use of high-frequency or unlicensed spectrum and cell densification for capacity increases call for adoption...

#### Comparative study of patch antenna loaded with slot split-ring resonators on different substrate materials

This paper presents square patch antenna loaded with slot split-ring resonators. Moreover, this paper discusses the performances of various dielectric substrates, having dielectric constants ranging from 2 to 5. Different substrate has been used to design the antenna such as Bakelite, Rogers RO 4232 and RT Duroid with dielectric constant of 4.8, 3.2 and 2.2, respectively. The...

#### A high-speed phosphorescent LED-based visible light communication system utilizing SQGNRC precoding technique

Peak-over-average power ratio (PAPR) control utilizing precoding technique based on square root-generalized raised cosine function is proposed and verified experimentally through a visible light communication system employing phosphor-based white light-emitting diodes for the first time. The simulation results show that the improved precoding matrix can further reduce PAPR by...

#### Improved dynamic routing algorithms in elastic optical networks

The considered Routing, Modulation Level and Spectrum Allocation (RMLSA) problem covers path length minimization while still meeting the spectrum continuity constraints, non-overlapping spectra constraints, spectrum contiguity constraints, and choice of modulation level. In this problem, the relationship between spectrum connection and bit rate of the incoming request has been...

#### Cost- and energy-efficient backhaul options for heterogeneous mobile network deployments

Heterogeneous networks (HetNets) have the potential to cater for the capacity requirements of mobile broadband services at reduced cost and energy consumption levels. One key aspect in HetNets is the role of the backhaul. More specifically, it is crucial for a mobile operator to understand the impact of specific technological and architectural upgrades in the mobile backhaul...

#### Design and performance evaluation of narrowband rectangular optical filter based on stimulated Brillouin scattering in fiber

We propose a rectangular optical filter based on stimulated Brillouin scattering (SBS) in fiber with tunable bandwidth from 50 MHz to 4 GHz at 15-MHz tuning resolution. The steep-edged rectangular shape of the filter is precisely controlled utilizing digital feedback compensation of the multi-tone pump light. The passband ripple is $$\sim$$1 dB by nonlinearity management of the...

#### Energy-efficiency versus resilience: risk awareness view on dimensioning of optical networks with a sleep mode

This article proposes to solve the trade-off between energy-efficiency and resilience with a focus on business mechanisms. Risk engineering is used as a foundation. Financial impact (penalty) quantification with various compensation policies is applied, and business-relevant risk measures are used during the risk assessment. Then, risk mitigation strategies are evaluated to...

#### Software defined elastic optical networking in temporal, spectral, and spatial domains

This paper discusses architecture, protocol, technologies, systems, and networking testbed for software-defined elastic optical networking in temporal, spectral, and spatial domains. By exploiting the progress in elastic optical networking (EON) in temporal and spectral domains utilizing dynamic optical arbitrary waveform generation and measurement technologies, and by extending...

#### A framework for deterministic delay guarantee in OBS networks

In OBS networks, the delay of control packets in the switch control unit (SCU) of core nodes influences burst loss performance in the optical switching and should be constrained. Furthermore, the end-to-end (E2E) delay requirements of premium services need queueing delay guarantee in network nodes throughout the transmission path. For this purpose, a framework for deterministic...
