This paper reports on hybrid III-V on silicon lasers, integrating one III-V active waveguide and two intra-cavity ring resonators. Such lasers are fabricated using a wafer bonding technique. By heating the two resonators, we achieve a thermal wavelength tuning range of 45 nm, with side mode suppression ratio higher than ...

Different precoder and equalizer structures have been proposed in literature for vectored digital subscriber lines (DSLs). In this paper, we assess the relative merit of advanced complex precoders and equalizers in practical DSL scenarios. Using extensive computer simulations, the achievable bit rates are investigated in the presence of alien crosstalkers, ...

Employing cloud computing technology within the energy sector to control critical grid elements poses unusual challenges to e.g. questions of scalability, availability and operating safety, including the protection against cyber-attacks of all kinds. Functionalities that would be essential for business-critical applications with real-time characteristics are oftentimes missing in todays commercial ...

A single molecule break junction device serves as a tunable model system for probing the many body Kondo state. There are predictions of universality across many realizations of the Kondo model in which the response of the system to different perturbations is characterized by a single emergent energy scale, k_BT_K. ...

In this paper we investigate the power consumption of IP-over-WDM optical networks as a function of 100 Gb/s Transponders (TXPs) transmission reach when the All-On and the On-Off planning approaches are considered. The former considers that transmission devices are kept always on and provides an upper bound to the network ...

Coordinated multipoint (CoMP) communication has been extensively considered to address the problem of inter-cell interference in cellular network. For uplink, to increase the cell edge users' throughput and to enhance network throughput, the signal from users are allowed to be received by more than one point that could be geographically ...

Wavelength-division multiplexing (WDM) has been the workhorse of data networks since the early 1990s, enabling ubiquitous and a ffordable data services with unabated exponential tra ffic growth. Today, commercial WDM systems can carry close to 10 Tbit/s over a single fi ber, and research experiments have reached the 100-Tbit/s mark. ...

In downlink multiuser MIMO systems, multiuser interference (MUI) can be suppressed by ZF-precoding or BD methods. However, the quantization error in channel information feedback generates additional multiuser interference, which can't be suppressed by precoders. As a result, the performance is significantly degraded and exploitation of multiuser diversity is limited. In ...

Non-Orthogonal Multiple Access Based on Superposition and Three-Index Assignment in a Rayleigh Fading Channel
- Schaepperle J.
The throughput in wireless cells using orthogonal multiple-access schemes like OFDMA is limited due to the fact that a significant part of the approximately mutually orthogonal radio resources are for fairness reasons assigned to users with high pathloss channels and therefore used with only low spectral efficiency. In this paper ...
