Résumé :

Second harmonic generation is a topic that attracts a lot of attention in photonics and has many applications (laser, microscopy, ...). On the other hand, integrated photonics is constantly emerging and is proving to be very interesting for nonlinear effects. It is therefore not surprising that researchers are bringing these two topics together to unite the best of both. One category of materials suitable for such experiments are therefore III-V materials. These materials have interesting properties for such a topic, such as high second order susceptibility and tunable bandgap.Thus, this thesis aims to gain a better understanding of second harmonic generation in III-V integrated structures.
