We report on site-controlled growth of InP/InGaP quantum dots (QDs) on GaAs substrates. Shallow nanoholes etched into a InGaP layer are used as nucleation sites for the QDs. Optimized growth conditions and the use of strain mediated nucleation allow us to realize QD arrays with excellent long range ordering on hole pitches as large as 1.25 µm. Single QD lines with an average linewidth of 553 µeV and...
We present high areal density GaxIn1-xP quantum dots grown on GaP substrate by molecular beam epitaxy and report a detailed structural and optical analysis. The composition dependent luminescence is evaluated and linked to the morphology.
The main driving force for customer acceptance of next-generation networks will be the availability of new and yet unknown multimedia services. The MediaBuilder platform fulfills this need by offering rapid service creation and deployment through an extensible set of service components. Initially, the platform was designed with the assumption of an asynchronous transfer mode (ATM) signaling-based...
