The conception and realisation of a prototype 355nm wind lidar return signal simulator capable of simulating the Rayleigh and the Mie return signals is described. The system is based on a commercial dual wavelength 1064nm/532nm diode pumped solid state las ...
The problem of energy optimization in multi-core systems (such as single-chip multiprocessors) where the individual energy demands of various processing elements are governed by instantaneous workload requirements is well defined in literature. The signifi ...
When designing a System-on-Chip (SoC) using a Network-on- Chip (NoC), silicon area and power consumption are two key elements to optimize. A dominant part of the NoC area and power consumption is due to the buffers in the Network Interfaces (NIs) needed to ...
Through silicon vias (TSVs) provide an efficient way to support vertical communication among different layers of a vertically stacked chip, enabling scalable 3-D networks-on-chip (NoC) architectures. Unfortunately, low TSV yields significantly impact the f ...
Vertical-cavity surface-emitting laser (VCSEL)-by-VCSEL optical injection locking to obtain high cutoff frequencies of 1.3-mu m VCSELs is demonstrated. A detailed physical explanation of the underlying mechanism is presented. VCSELs from the same wafer hav ...
Research on Networks on Chips (NoCs) has spanned over a decade and its results are now visible in some products. Thus the seminal idea of using networking technology to address the chip-level interconnect problem has been shown to be correct. Moreover, as ...
Injection locking of two DFB semiconductors opens new possibilities to generate effective signals for optical sensing, in order to reach better performances. Pure wave forms can be generated with qualities exceeding those obtained using external modulators ...
Frequency stabilization is generally performed by using atomic or molecular absorption lines. However, it is sometimes necessary to lock a laser at a frequency located outside of any absorption peaks. In this case, an offset locking configuration is necess ...
Injection locking of two DFB semiconductors opens new possibilities to generate effective signals for optical sensing, in order to reach better performances. Pure waveforms can be generated with qualities exceeding those obtained using external modulators. ...
