Nanostructured Efficient White LEDs based on short-period superlattices and quantum dots (NEWLED)
Date du début: 1 nov. 2012, Date de fin: 31 oct. 2016,
NEWLED will develop high efficiency and high brightness monolithic and hybrid all-semiconductor WHITE light-emitting GaN-based diodes. Power losses due to phosphor conversion and the problem of different ageing rates of the GaN LED pump will be eliminated by the development of phosphor free structures with increased brightness (power emitted per surface per angle). NEWLED will enhance the efficien ...

High Brightness COnical REfraction Lasers (HICORE)
Date du début: 1 oct. 2012, Date de fin: 30 sept. 2014,
A fundamental property of lasers is the ability to propagate and be focused to very small spots with little divergence, termed beam quality. The ability to achieve high power low divergence operation (high brightness) is of paramount importance for many applications, both existing and potential, of laser devices. Effective ways to scale output power without compromising beam quality are limited ...

COMPACT ULTRAFAST LASER SOURCES BASED ON NOVEL QUANTUM DOT STRUCTURES (FAST-DOT)
Date du début: 1 juin 2008, Date de fin: 31 août 2012,
FAST-DOT aims to implement a new range of ultrafast quantum-dot lasers for critical bio-medical applications. This project will develop portable, low-cost, reliable, highly efficient ultrashort pulse and ultra-broadband tuneable laser sources. The key technical innovation – quantum dots (QDs) - are based on novel semiconductor nanostructure clusters which demonstrate remarkable new photonic prope ...
