ANR – JST joint call for two CREST research areas: “Quantum technologies”

JST and the French National Research Agency (Agence Nationale de la Recherche; “ANR”) concluded a Framework Agreement in December 2017.

The purpose of this Agreement is to foster Japanese-French collaboration in scientific research and to fund joint research projects conducted by Japanese and French partners eligible for funding from each agenc on:
Quantum technology: Creation of an innovative quantum technology platform based on the advanced control of quantum states

The full description of the two areas is appended to the document on the national regulations for French applicants.

The proposals should be led by a Japanese PI and a French PI and will be evaluated via a peer-review procedure by JST and ANR. The call is open to public and private partners.

The average ANR funding will be around 500 k€ per project depending on the number of partners and the ambition of the project, for a 5-year duration.

The JST-CREST call will be launched at a later date for non-joint proposals but the Japanese-French consortia must have submitted their proposals to ANR website before April 16th, 10AM CET.

30 June 2017 – Thesis defense of Nicolas VON BANDEL

Nicolas VON BANDEL will defend his thesis on 30 June 2017 at 14:00, 0C-140 (Auditorium) – III-V Lab Campus Polytechnique 1 avenue Augustin Fresnel 91767 Palaiseau on the subject “Development and study of low noise laser diodes emitting at 894 nm for compact cesium atomic clocks”. This work was a collaboration between Institut d’Electronique et des Systèmes (Montpellier) and III-V Lab (Palaiseau).

Abstract : This PhD work deals with the design, the fabrication and the study of high-coherence semiconductor laser sources emitting at 894 nm, for application to compact, optically-pumped cesium atomic clocks in an industrial context. We are particularly interested in the electrically pumped ”Distributed-Feedback” in-plane laser diodes (DFB). The aim is to obtain a low-threshold, single-mode laser with high optical efficiency and a linewidth of less than 1 MHz. We first deal with the design and first-order characterization of the DFB diodes until they are put into modules for the clock. We then carry out an in-depth study of the physical properties of the laser emission in terms of coherence time. For that purpose, a new universal method for characterizing the optical frequency noise is introduced. Finally, we look further into the spectral properties of the emission in a servo configuration on a fluorescence line of the cesium (”Dither-Locking”). We show that the intrinsic properties of the component satisfy the requirements of the industrial system as defined in the study.

Keywords : Laser diodes, low noise, 894nm, cesium atomic clocks, frequency noise metrology, linewidth in servo

Workshop on Optical Materials by SCHOTT, HERAEUS and HELLMA

Within the framework of the CNES CCT “Optics and Optoelectronics Technical Center” and the “Material Technical Center”, a Workshop on Optical Materials by SCHOTT, HERAEUS and HELLMA, will be organized on 22nd & 23rd June 2017 at CNES (Room Leonard de Vinci), Toulouse.

The first day (Thursday 22nd june) will be about all optical materials: Optical Glass, Filter Glass, Coated Filters, Fused Silica and Calcium Fluoride

The second day (Friday 23rd june) will be dedicated to Zerodur® and Infrared optical materials.

The attached agenda details the different items that will be presented. Questions and open discussions will conclude each point.
