This is a project coming from industry that intends to develop in the COST 288 frame. It addresses the implementation of nanostructured semiconductor gain materials (quantum dots) for development of novel light sources having clear industrial application potential. Quantum dot superluminescent light-emitting diodes operating around 1300 nm will be pursued. On the scientific side, the expected outcome is added insight in the link between physical properties of quantum dots and fabrication techniques as active semiconductor light sources. This point will be pursued in a close collaboration with university groups in COST. On the industrial application side, improved performance and significant cost saving as compared to traditional light emitting diodes are expected.

Abstract
(English)
|
This is a project coming from industry that intends to develop in the COST 288 frame. It addresses the implementation of nanostructured semiconductor gain materials (quantum dots) for the development of novel light sources having clear industrial application potential. In particular quantum dot superluminescent light-emitting diodes (SLEDs) operating around 1300 nm are pursued. On the scientific side, the outcome adds insight into the link between physical properties of quantum dots and fabrication techniques as active semiconductor light sources. We are closely collaborating with university groups from the COST288 forum. On the industrial application side, the motivation lies in the expected improved performance when compared to traditional light emitting diodes. In particular a larger spectral emission bandwidth and a lower temperature dependence of the output power are expected. Based on the results from the previous 2 years, we continues to optimise the design of quantum-dot based SLEDs with the goal to increase optical output power and spectral width. We were able to demonstrted SLEDs emitting.
