Expérimental
The aim of this PhD thesis will be to develop THz plasmonic cavities and to study their nonlinear behaviour when subjected to intense THz pulses. A main goal of the project will be to realize analogues of nonlinear optics in the THz frequency range, such as harmonic generation, parametric conversion, optical bistability, etc. Overall, this would allow to help bridging the so-called “THz gap”. The project will cover aspects such as the design, the fabrication and the measurement of plasmonic resonators. The experimental studies will be a complemented with numerical simulations, both in the linear and nonlinear regime of light matter interaction.
