A novel low-cost photonic PON-to-RoF bridge is presented, allowing simultaneous wireline and wireless multi-Gbps data transmission with minor impact on deployed PON networks. Simulation results show that the proposed scheme does not require narrow-linewidth lasers when envelope detector mobile terminals are used, since the transmission performance is not limited by the phase noise but by the RIN and the frequency difference between the two beating lasers.

We report on surface-wave propagation (SWP) that occurs in semi-infinite hyperbolic metamaterials whose optical axis is set in the interface plane. In practice it is implemented by a multi-layered metal-dielectric nanostructure that is cut normally to the layers. Our theoretical analysis shows that various conditions can be designed enabling distinct regimes of SWP. We concluded that hybridization of SWP polarization leads to tighter confinement near the interface as compared with conventional surface plasmon polaritons. By using the finite-element method (FEM), we demonstrate that the fields are enhanced on the walls of metallic films, and thus minimizing significantly its presence inside the metal. This leads to the reduction of dissipation in the lossy metamaterial and allow for the existence of long-range surface waves that propagate obliquely to the optical axis. This suggests applications in nanosensing and nanoimaging.

We present an experimental analysis on externally seeded colourless transmitters for WDM PON. We take advantage of direct modulation of a high performance MQW RSOA. Chirp is analysed as main limiting factor to SSMF propagation at 10 Gb/s. We demonstrate that off-set filtering performed by the OLT demultiplexer allows to cope with chromatic dispersion impairments and to bridge 24-km SSMF at 10 Gb/s with modest penalties with respect to back to back.

It is shown that dipolar coupling between neighboring quantum dots enhances the absorption of light in close packed monolayers of colloidal quantum dots. Based on this concept, the experimentally determined losses in planarized waveguides coated by a quantum dot monolayer can be successfully simulated. These simulations rely on replacing the quantum dot layer by an effective medium with a dielectric function determined by dipolar coupling and use the dielectric constant of the quantum dot host medium as the only adjustable parameter. This leads to a generic approach for the simulation of optical materials including close packed quantum dot layers.

In this paper, the flexible features of bandwidth variable transponders based on OFDM technology are investigated. The limiting factors due to the subsystem components and the trade-off between cost-effectiveness, capacity and reach are taken into account for designing this fundamental building block of elastic optical networks. Advanced functionalities, including sliceability, are discussed. Performance is analysed by means of numerical simulations. Furthermore, the experimental results, achieved within the EOS platform (Experimental platform for Optical OFDM Systems) of the ADRENALINE testbed, are presented.

The ab-initio quantum mechanical calculations (time-dependent Hartree-Fock (TDHF) method) of a series of ruthenium complexes have been carried out to compute electric dipole moment (μ), dispersion-free and frequency-dependent first hyperpolarizability (β) values. The one-photon absorption (OPA) characterizations have been also theoretically investigated by means of configuration interaction (CI) method. Our calculated results on the maximum OPA wavelengths and second-order hyperpolarizabilities are in good agreement with the observed values in the literature. According to the results of the TDHF calculations, the investigated molecules exhibit non-zero β values, and they might have microscopic second-order nonlinear optical (NLO) behaviour. We also give the computational results of the frequency-dependent second-order susceptibilities (χ(2)) for the examined compounds. The calculated results on dynamic (χ(2)) are quite consistent with the previous experimental observations.

An increasing number of studies about flexgrid-based elastic optical networks are currently being carried out by industry as well as academic research teams. As access to real test-beds is limited, there is a lack of effective tools that emulate realistic scenarios for testing algorithms and network architectures. In this paper, we present a simulation framework based on an active stateful Path Computation Element (PCE) with Global Concurrent Optimization (GCO) for flexgrid optical networks. The simulator is fully configurable and allows implementing and testing new algorithms and architectures easily and quickly.

In a fast changing world where information technology drives economic prosperity, the number of data centres has grown significantly in the past few years. These data centres require large amount of energy in order to meet up with increasing demands. An overview of energy efficient optical interconnects as a means of reducing energy consumption without compromising speed and accuracy was presented. New methods by which energy efficiency can be achieved using OCDMA multiplexing techniques for future optical interconnections were discussed. We also presented some challenges that might inhibit effective implementation of the OCDMA multiplexing scheme.

Since several decades, angular velocity sensors are considered crucial devices in a wide range of vehicles such as military and civil airplanes, military ships, submarines, satellites, space launchers, and long-range ballistic missiles. The interest towards miniaturized gyroscopes for aerospace and defense industry has given rise to an increasing research effort aiming at the scaling of optical gyros through integrated optical technologies. In particular, the resonant optical gyro (ROG) has been identified as the ideal candidate for a new generation photonic angular velocity sensor. Two technological approaches are available to implement the ROGs, i.e., the hybrid integration of optoelectronic components manufactured on different substrates or the monolithic integration of all components on a single chip. The two options are critically discussed and compared in this paper with a special attention on integrated gyroscopes (gyro-on-a-chip, GoC) in silica on silicon and indium phosphide that have been recently theoretically and experimentally studied, demonstrating promising results.

Multimode fiber (MMF) links are currently attracting much interest as a medium for the transmission of radio signals over optical links called Radio over Fiber (RoF) link. However, the application is restricted, because the capacity of MMF transmission is limited by intermodal dispersion which is caused by the different propagation speeds of the fiber modes. The free space propagation of radio waves has a similar effect caused by multipath wave propagation. However, to overcome that effect a promising candidate is the orthogonal frequency division multiplexing (OFDM) method which has been rapidly and widely adopted in wireless, wire-line and broadcast systems for efficiently dealing with linear signal distortions encountered when transmitting over fading channels. Therefore, OFDM has recently gained significant attention in access networks. In this paper OFDM signals will be applied to investigate a Radio over MMF link. By using OFDM equalization the dispersion of the transmission system can be well estimated and mitigated, hence the distortion of the multimode dispersion can be compensated. The compensation method will be demonstrated for graded index (GI) and step index (SI) fibers as well. Performance of the transmission will be analyzed; it is investigated for different fiber lengths, fiber types, optical source types; and the optimal OFDM parameters will be determined.
