Methods for bounding genetic nonlinearities
Complex hierarchical structures are a hallmark of life. Within multicellular organisms, the building blocks of these structures are cells; within cells, they are genes. The interdependence of these building blocks is difficult to measure but is integral to the biological processes of health and …

Second order nonlinearities in silicon photonics
In this thesis, second order optical nonlinearities in silicon waveguides are studied. At the beginning, the strained silicon platform is investigated in detail. In recent years, second order nonlinearities have been demonstrated on this platform. However, the origin of these nonlinearities was not …
