Influence of 2D matrix patterning on electro-optical performances of GaN LEDs for ultra-high brightness emissive microdisplays.

Offer N°: SL-DRT-14-1161

Start date: 1 Dec 2014

The aim of the work is to investigate, modelize and optimize influence of matrix-patterning on electro-optical performances of GaN LED microsources for the realization of high resolution and high-brightness emissive microdisplays. The objective is to design and realize micrometric GaN LED sources with electro-optical efficiency comparable to those of large-size conventional LED for lighting applications, despite the constraints of the small-dimensions.



[Thesis]

Design of electronically reconfigurable transmitarray antennas at mm-wave frequencies

Offer N°: SL-DRT-14-1157

Start date: 1 Nov 2014

High gain electronically reconfigurable antennas with beam-steering, multi-beam, and beam-forming capability are required in a huge number of emerging applications for radar, sensing, and communication systems (civil and military) typically ranging from C-band (4-8 GHz) to W-band (75-110 GHz).



[Thesis]

Development of ultra fine pitch interconexion array

Offer N°: SL-DRT-14-1185

Start date: 1 Dec 2014

The Optics and Photonics Department of CEA/LETI is involved in the assembly of imaging components (such as Infrared detectors or microdisplays) on CMOS circuits. In this area one of the driving element for a better resolution is the pitch reduction. If some interconnection technologies exist, the assembly of components with an ultrafine pitch (<5-10µm) requires new development.
