Fri 27-03-2015 DTU-forskere laver verdens hurtigste optiske chip
For første gang nogensinde er det lykkedes med en ren optisk chip at konvertere terabit/s-signaler fra en bølgelængde til en anden.

Wed 18-03-2015 Briterne satser stort på kvanteteknologi med brug af danske lasere
NKT Photonics har i international konkurrence vundet en ordre på levering af fiberlasere til et nyt Quantum Hub ved britiske universiteter. De skal bl.a. bruges til udvikling af nye kvanteteknologier til monitorering af oliereservoirer.

Mon 16-03-2015 Wavetouch: Dansk teknologi kan gøre din smartphone endnu bedre
Er der noget mere irriterende, end når din smartphone nægter at reagere, måske fordi du har våde fingre? WaveTouch er en ny optisk teknologi, der kan revolutionere markedet for touch-skærme

Mon 16-03-2015 Danske forskere gemmer solens stråler i væsker
Ved at overføre energien fra solens stråler direkte ved hjælp af elektrokemi vil danske og portugisiske forskere gemme el i en tank med elektrokemiske væsker. Energi kan så trækkes ud af væskerne via et såkaldt flowbatteri.

Mon 16-03-2015 Creating Lasers in the Sky
Collaborators working at labs in Russia, Austria, and the United States have succeeded in pumping more than 200 gigawatts of power into a 0.1-millimeter-wide filament formed in the ambient air by a laser.

In a paper published in the 17 February issue of Scientific Reports, they describe how they created laser pulses in the mid-infrared part of the spectrum.

Mon 16-03-2015 Kraftig laserkanon gennemskærer bil
Den amerikanske våbenproducent Lockheed Martin har udviklet et nyt laservåben, der er langt mere kraftfuldt og præcist end noget tidligere prøvet system.

Thu 19-02-2015 Provably secure and practical quantum key distribution over 307 km of optical fibre
Here, we present, for the first time, a compact and autonomous QKD system that is capable of distributing provably secure cryptographic keys over 307 km of optical fibre. This is achieved by using semiconductor single-photon detectors with record low background noise and a novel finite-key security analysis, which is efficient even for short key lengths. This demonstrates the feasibility of practical long-distance QKD based on standard fibre-optic telecom components.

Thu 19-02-2015 Nonlinear Optics: Principles and Applications
New book out by Karsten Rottwitt and Peter Tidemand-Lichtenberg explores the fundamental aspects of nonlinear optics.

As nonlinear optics further develops as a field of research in electromagnetic wave propagation, its state-of-the-art technologies will continue to strongly impact real-world applications in a variety of fields useful to the practicing scientist and engineer.

Wed 11-02-2015 The Challenge of Complexity
Please join us for the exciting talk by Peter Cochrane on Friday 20.02.2015 from 13.00 in 306/37 at DTU.

We have gathered a few details about the talk (and Peter).

Sat 31-01-2015 In Memoriam: Charles Hard Townes
The 1964 Nobel Prize inventor of the maser (microwave amplification by stimulated emission of radiation), Dr. Charles Hard Townes, died early on January 27 at age 99.
