Fabrication and characterization of MEMS alkali vapor cells used in chip-scale atomic clocks and other atomic devices

Karlen, Sylvain ; Mileti, Gaetano (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Atomic clocks are timekeeping devices that can achieve extreme performance in terms of stability and accuracy. Behind this name, hides a variety of different systems which size and complexity can be considerably different depending on their applications. The primary frequency standards used for the realization of the second and the clocks mounted on the Galileo satellite positioning system are...

MEMS-based mirror array for astronomical instrumentation

Waldis, Severin ; Rooij, Nico de (Dir.) ; Herzig, Hans Peter (Codir.) ; Noell, W. (Codir.) ; Shea, H. (Codir.) ; Zamkostian, F. (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2010.

The NASA’s and ESA’s James Webb Space telescope program, the development of the European Extremly Large Telescope (E-ELT) and the European Cosmic Vision program bring into fashion what astronomy always wanted to do, explaining where we are coming from by studying the formation of the galaxies and their evolution. Two requirements become a necessity: multiplexing and high spatial resolution...

Study and fabrication of a micro scanner for optical applications

Pétremand, Yves ; De Rooij, Nicolaas-F. (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2008 ; Th.2022.

Being currently performed on highly complex and expensive equipments, active optical alignment of single mode 10Gb/s transmitters and receivers is proving to be the bottleneck process for high volume manufacturing. In order to alleviate this production burden, new integrated technologies are required to align micro-components like micro-lenses and optical fibers with photonic devices. Although...
