La digitalisation du transfert de connaissances tacites

Kuenlin, Simon ; Fragnière, Emmanuel (Dir.)

Mémoire de bachelor : Haute Ecole de Gestion & Tourisme, 2020.

La problématique de ce travail repose sur la question : « Est-il possible d’effectuer un transfert de savoir-faire (connaissance tacite) en groupe par l’utilisation d’outils digitaux ? » Pour répondre à cette question, j’ai réalisé des entretiens semi-dirigés auprès d’un échantillon de douze personnes : six entretiens ont été menés avec des fournisseurs de workshop et...

Towards compact ultralow phase noise lasers and microwave signals based on new approaches

Brochard, Pierre ; Südmeyer, Thomas (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2019.

Today, the lowest phase noise microwave signals are generated optically by frequency division of an ultra-stable optical reference using a femtosecond frequency comb. In the commonly used approach, the ultra-stable optical reference is obtained by frequency-stabilizing a laser to a high-finesse ultra-low expansion optical cavity, and the frequency division is performed by optically locking a...

Semiconductor disk laser-based frequency combs

Jornod, Nayara ; Südmeyer, Thomas (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

This thesis studies the first self-referenced frequency combs based on modelocked semiconductor disk lasers (SDLs). The generation of stabilized frequency combs based on ultrafast lasers has been a significant breakthrough for many applications in various fields of physics, spectroscopy and metrology. Optical frequency combs can serve as a frequency ruler that provides a direct and...

Measurement of the linewidth enhancement factor of singlemode room temperature continuous wave quantum cascade lasers

Aellen, Thierry ; Aebi, Philipp (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2008.

The invention of the laser source in 1960 has led to a wide range of applications showing a widespread impact in every aspect of our today life, including for example hospital, factory or simply at home. In particular, recent developments originating from the compact, highly efficient and common semiconductor lasers that are simply supplied by an electrical current. The diode coherent light...
