Zero Order Dimension based Industrial components Applied to teleCommunications

Project description


Materials, Equipment and Processes for Production of Nano-Photonic and Nano-Electronic Devices

Self assembled semiconductor quantum dots (QDs) constitute a class of nanoscale materials which provide fundamental advantages compared to the currently dominating 2D quantum wells: first, the zero dimensional dots suppresses temperature effects on laser threshold and efficiency and results also in a strongly reduced back reflection sensitivity. Secondly, QDs provide new degrees of freedom regarding the monolithic combination of materials. Both features are expected to allow the fabrication of compact, coolerless and isolator free telecom laser modules, providing important cost advantages in a highly competitive international market. The 8 partners of the consortium include leading European semiconductor laser manufacturers and system providers which team up with expert SMEs and academic institutions in an integrated effort to push quantum dot materials at a manufacturable level. Although some promising features of QD lasers have already been demonstrated, there are several important material challenges to be resolved including -realization of device grade QDs on InP -nanoengineering InGaAs QD properties on GaAs and InP specifically for high speed directly modulated lasers, widely tuneable lasers and semiconductor amplifiers, with specifications clearly exceeding currently available QW based devices performance, -realization of device grade 1.55 �m emitting QDs on GaAs, -development of injection structures for 40 Gbit/s directly modulated QD lasers -exploration of new QD based concepts, based on e.g. the Pockel�s effect -detailed investigations QD device reliability according to telecom standards. At the end of the project the consortium envisages to have reached a qualitatively new level of control in the fabrication of self assembled semiconductor nanostructures. The industrial partners of the project see this as a decisive step for a wide commercial exploitation of QD lasers which will greatly enhance their competitiveness.
