<strong>Background</strong><br> Compact state of the art 3R-regeneration systems for an optical phase-coded data signal are not capable of enhancing the quality of phase information. Since DPSK systems offer 3 dB better performance, phase-coded systems and thus phase regeneration would be favourable in all-optical networks. <br><br> <strong>Technology</strong><br> This technology allows the entire, all-optical regeneration of DPSK and other phase-coded optical data signals under a conversion of the carrier wavelength. The compact design of the regeneration module opens the possibility to easily integrate it into an optical sub-system avoiding fiber technology. The method also offers the possibility of converting the phase-coded optical signal into an amplitude-coded optical signal. This can be operated independently.<br><br> <p><strong>Benefits</strong><br> <ul> <li>All optical phase regeneration</li> <li>Compact design possible</li> </ul> <p><strong>IP Rights</strong><br> German Patent DE 10 2005 037 828</p> <p><strong>Origin</strong><br> Technische Universität Berlin, Germany</p>

International team of scientists develops new feedback method for optimizing the laser pulse shapes used in the control of chemical reactions
In many ways, traditional chemical synthesis is similar to cooking. To alter the final product, you can change the ingredients or their ratio, change the method of mixing ingredients, or change the temperature or pressure of the environment of the ingredients.
Like an accomplished chef, chemists have become very skilled ...
A genetic defect protects mice from infection with influenza viruses
A new study published in the scientific journal PLOS Pathogens points out that mice lacking a protein called Tmprss2 are no longer affected by certain flu viruses.
The discovery was made by researchers from the Helmholtz Centre for Infection Research (HZI) in Braunschweig in collaboration with colleagues from Göttingen and ...
The Light: Global study gets underway with online user survey
Light has a fundamental impact on our sense of well-being and performance. In cooperation with Zumtobel, a supplier of lighting solutions, Fraunhofer IAO has launched a global user survey of lighting quality in offices. The objective is to identify the best lighting conditions for a variety of spaces and lighting ...
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived.
Physicists at the University of Washington and Stony Brook University in New York believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another.
But here’s the catch: One couldn’t actually ...
A star is formed when a large cloud of gas and dust condenses and eventually becomes so dense that it collapses into a ball of gas, where the pressure heats the matter, creating a glowing gas ball – a star is born.
New research from the Niels Bohr Institute, among others, shows that a young, newly formed star in the Milky Way had such an explosive growth, that it was initially about 100 times brighter than it is now. The results are published in the scientific journal, Astrophysical Journal Letters.
The young ...
