Entanglement dynamics of photon pairs and quantum memories in the gravitational field of the earth
/en/research/publications/entanglement-dynamics-of-photon-pairs-and-quantum-memories-in-the-gravitational-field-of-the-earth
We investigate the effect of entanglement dynamics due to gravity – the basis of a mechanism of universal decoherence – for photonic states and quantum memories in Mach-Zehnder and Hong-Ou-Mandel…
Correlating Interface and Border Traps With Distinctive Features of C–V Curves in Vertical Al2O3/GaN MOS Capacitors
/en/research/publications/correlating-interface-and-border-traps-with-distinctive-features-of-c-v-curves-in-vertical-al2o3gan-mos-capacitors
In this article, we present an analysis of the correlation between interface traps (ITs) and border traps (BTs) on distinctive features of C–V curves in vertical Al2O3/gallium-nitride (GaN) MOS…
Advanced in-situ etch depth control for dry etching processes – to achieve optimum device perfor-mance
/en/research/research-news/advanced-in-situ-etch-depth-control-for-dry-etching-processes-to-achieve-optimum-device-perfor-mance
Sophisticated etch processes are required to fabricate high-power diode lasers with excellent performance. We explain exemplarily how to control the etch depth in-situ and why the measuring…
Process optimisation of MOVPE growth by numerical modelling of transport phenomena including thermal radiation
/en/research/publications/process-optimisation-of-movpe-growth-by-numerical-modelling-of-transport-phenomena-including-thermal-radiation
A global transport model for the MOVPE of III–V growth based on the finite volume solution of coupled flow, heat and mass transfer, including detailed radiative transfer, multicomponent diffusion and…
The effective frequency method in the analysis of vertical-cavity surface-emitting lasers
/en/research/publications/the-effective-frequency-method-in-the-analysis-of-vertical-cavity-surface-emitting-lasers
An effective index model for vertical-cavity surface-emitting lasers (VCSEL's) is reexamined. In a systematic manner, the basic equations are derived. Instead of effective indices of plane reference…
Guest Editorial Special Issue on Globalization in Photonics
/en/research/publications/guest-editorial-special-issue-on-globalization-in-photonics
We highlight in this special issue some of the excellent work and advances in photonics which are taking place world-wide. The papers also emphasize how the photonics field in general and the…
