Theoretical seminar | 09 February 2022

Nonlinear effects associated with frequency conversion are fundamental physical processes that underlie many modern applications, including medical bioimaging up to characterization of materials and nanotechnology. Nonlinear optics opens up great prospects in the field of laser physics with applications in information technology for optical signal processing and in the development of new sources of coherent light. The ability to efficiently generate harmonics at the nanoscale is of great importance for future applications, as it allows the creation of much more compact devices and the study of structures of limited dimensions. One of the new and promising candidates is halide perovskite devices, as they have excellent electrical and optical properties, demonstrated in the linear optical mode. I will present the current results for CsGeI3 particles and talk about future plans in this area.
