Position Description
Proposed Projects
Option 1
Study of Liquids with Quadratic Nonlinear Optical Methods
Understanding the molecular organization of liquids is of utmost importance in a broad range of domains, from planetary and environmental sciences to more applied research like solvation and battery electrolytes. This endeavor requires new concepts and new instruments to isolate intermolecular interactions and observe ion solvation or aggregation.
The project aims at conceiving new concepts and designing new instrumentation to achieve these aims using nonlinear optics based protocols. In particular, innovative strategies based on frequency doubling and sum- or difference- frequency mixing will be proposed and enabled, building on the already known skills of the research group where the work will be conducted. A special emphasis will be given towards near-IR and Mid-IR spectral domains where compounds have distinct optical fingerprints.
Option 2
Analysis of Compounds with Cubic Nonlinear Optical Methods
Detection and characterization of (bio-)chemical based compounds and materials has become of utmost importance in a broad range of domains, from environmental and security monitoring to climate science and astrophysics. This endeavor requires new concepts and new instruments, with a special emphasis towards near-IR and Mid-IR spectral domains where compounds have distinct optical fingerprints.
The project aims at conceiving new concepts and designing new instrumentation to achieve these aims using nonlinear optics based protocols. In particular, innovative strategies based on third order nonlinear optical methods like two-photon excited fluorescence and nonlinear absorption-refraction fundamental mechanisms will be proposed and enabled, building on the already known skills of the research group where the work will be conducted.
Option 3
New concepts with Nanoparticles for Sensing with Nonlinear Optical Processes in the NIR-MIR
In order to perform the detection and characterization of (bio-)chemical based compounds and materials at ultra-low level with applications in a broad range of domains from environmental and security monitoring to climate science, one strategy is to use nanoparticles as vectors with high sensitivity and selectivity. This strategy can involve either dielectric or plasmonic nanoparticles and may possibly entail surface chemistry in order to target specific analytes. This endeavor requires new concepts and new instruments, with a special emphasis towards near-IR and Mid-IR spectral domains where compounds have distinct optical fingerprints.
The project aims at conceiving new concepts and designing new instrumentation to achieve these aims using nonlinear optics based protocols.
