We hope you had a fantastic start into 2015! We are looking foward to an inspiring year with pioneering ideas, 
exciting applications and  a lot of new products to come. Let's get started:

Award-winning cryogenic photolithography

The French group around Dr. Pascale Senellart at the LPN at CNRS has pioneered cryogenic in-situ optical lithography for manufacturing microcavities around single quantum dots. This allows for the deterministic production of electrically tunable and very bright single photon sources, with a yield increase by a factor of about 10.000 compared to previous approaches. For this remarkable achievement, she recently received the Médaille d’argent du CNRS 2014 (Silver Medal of Physics).

Based on her group’s work, attocube designed a three channel cryogenic confocal microscope, which has turned into a heavily used instrument in her laboratory. Many researchers in the world are currently benefiting from the photon sources produced by the system.

attoDRY700 - Valley polarization dynamics

The group of B. Urbaszek in Toulouse is working in the field of 'valleytronics' using monolayers of transition metal dichalcogenides. In this report, they present time-integrated, as well as time-resolved photoluminescence results for monolayer WSe2 in a micro-PL setup based on an attoDRY700 cryostat and our Premium Line positioners.

Their results demonstrate the robustness of the optically generated valley polarization through the nanosecond decay time of the trion polarization. This stable valley polarization will allow to further progress the understanding of the interaction between monolayer TMDCs and polarized light for applications and fundamental research.

ISO certification for quality & environmental management

Last month, attocube received the ISO 9001 certification for Quality Management Systems as well as the ISO 14001 certification for Environmental Management Systems. 

"The focus on the highest quality products and customer satisfaction has been central to our business ever since the foundation of attocube" states CEO Dr. Dirk Haft. "We are very pleased that the integration of these standards and our commitment to uncompromising quality & sustainability are now also officially confirmed by an independent, globally acknowledged organization".
