Crystalline materials are excellent substrates for the integration of compact photonic devices benefiting from the unique optical properties of these materials. The technique of direct inscription with femtosecond lasers, as an advantage over other t

Thermodynamics of the electrical response in band insulators - Synchronisation and spin-echo in cold atom gases

Autor: Combes, Frédéric

Publikováno v: Matière Condensée [cond-mat]. Université Paris Saclay (COmUE), 2018. Français. ⟨NNT : 2018SACLS540⟩

The work exposed in this manuscript covers two distinct topics. The first is about the response of crystalline dielectrics to an external static electric field; it is based on King-Smith, Vanderbilt and Resta modern theory of polarisation. Restrictin

Orientation-dependent multiphoton ionization in wide band gap crystals

Publikováno v: Physical review letters. 101(24)

Using different crystalline dielectrics and intense femtosecond laser pulses, we show that nonlinear absorption depends on sample orientation. This arises primarily because of the direction dependence of the effective mass of the electron. The multip
