Wed 10-12-2014 Kraftig laser rydder togskinner for nedfaldne blade
I et forsøg har de hollandske jernbaner monteret lasere foran toghjulene, så togene kan brænde sig vej gennem efterårets store årsag til forsinkelser: Løvfald.

Tue 25-11-2014 Snoet lys kan mangedoble datahastigheden
Et nyt eksperiment viser, at snoede lasersignaler kan sendes uforstyrret gennem atmosfærisk luft.

De seneste år har flere forskningsgrupper verden over taget hul på en ny teknik til at øge kapaciteten af eksisterende kommunikationskanaler. Det går populært sagt ud på at sno elektromagnetiske bølger på en særlig måde, så information kan sendes med forskellige grad af snoning over samme fysiske kanal.

Princippet kan udnyttes både for laserlys i det optiske eller infra­røde område og for radiobølger ved frekvenser, der anvendes til mobilkommunikation.

Teknikken er afprøvet både gennem luften og i en optisk fiber produceret i Danmark.

Fri 07-11-2014 Ultra-high-density spatial division multiplexing with a few-mode multicore fibre
Single-mode fibres with low loss and a large transmission bandwidth are a key enabler for long-haul high-speed optical communication and form the backbone of our information-driven society. However, we are on the verge of reaching the fundamental limit of single-mode fibre transmission capacity. Therefore, a new means to increase the transmission capacity of optical fibre is essential to avoid a capacity crunch.

We look forward to the DOPS General Assembly 2014, and hope to see many DOPS members at the assembly. Use this opportunity to let the DOPS board know, which events within optics and photonics you would like DOPS to arrange.

Sat 11-10-2014 Biophotonics 15
The 7th International Graduate Summer School Biophotonics '15 will take place 6–13 June 2015 at Backafallsbyn on the Island of Ven, Sweden.

We have an exciting list of topics and lecturers that already have confirmed their participation. The lecturers will teach their topics in the usual four hour sessions each. In addition to these lectures, the school will kick-off with a keynote lecture on a selected theme; in 2015 entrepreneurship is highlighted.
