Optical feedback tolerance is experimentally investigated on a 600-mu m-long quantum-dash based Fabry-Perot laser emitting at 1.57 mu m.
Sharing patterns in shared-memory multiprocessors are the key to performance: uniprocessor latency-tolerating techniques such as out-of-order execution and non-blocking caches have proved unable to
This memo documents part of the work performed on our 1987 IR&D effort.
To resolve the controversy over whether the increasing quantities of carbon dioxide in the atmosphere have produced observable changes in the climate, we apply modern methods of data analysis to th
In dual- or multiple-channel synthetic aperture radar (SAR) imaging modes, cross-channel correlation is a potential source of information.
Low coherent light interferometry requires broad bandwidth light sources to achieve high axial resolution.
Time series analysis of low-energy electron and high-energy proton cosmic ray fluxes, both measured on the Ulysses spacecraft, shows that they are quite coherent in some frequency bands in the ener
We experimentally demonstrate transmission of 6 mode-multiplexed 20-GbdQPSK signals over 1200 km of coupled-core fiber (CCF).
We experimentally demonstrate transmission of 6 mode-multiplexed 20-Gbd-QPSK signals over 1200 km of three-core microstructured fiber (3C-MSF).
Underwater acoustic communication link performance is investigated under strong time-frequency variation.
