Nonlinear and electro-optic devices are present in our daily life with many applications: light sources for microsurgery, green laser pointers, or modulators for telecommunication. Most of them use bulk materials such as glass fibers or high-quality crystals, hardly integrable or scalable due to low signal and difficult fabrication. Generating nonlinear or electro-optic effects from materials at the nanoscale can expand the applications to biology as imaging markers or sensors, and to optoelectronic integrated devices. However, the efficiency of nanostructures is low due to their small volumes.
In this webinar hosted by the OSA Photonic Metamaterials Technical Group, Rachel Grange from ETH Zurich will show several strategies to enhance optical signals by engineering metal-oxides at the nanoscale with the goal of developing nonlinear and electro-optic photonics devices for a broad spectral range and over large surface area.
What You Will Learn:
- Nonlinear and electro-optic effects at the nanoscale
- Fabrication of integrated devices from nanoparticles
About the Presenter: Rachel Grange, ETH Zurich
Since 2021, Rachel Grange is an associate professor in the field of integrated and nanophotonics in the Department of Physics at ETH Zurich (Switzerland). She has been Assistant Professor at ETH Zurich since 2015. From 2011 to 2014, she was junior group leader at the Friedrich Schiller University in Jena (Germany). During her post-doc at EPFL (Switzerland), she worked on nonlinear bioimaging with metal-oxides nanoparticles from 2007-2010. She received her Ph.D. in 2006 from ETH Zurich on ultrafast laser physics. Her research covers material investigations at the nanoscale, top-down and bottom-up fabricated nanostructures with metal-oxides. Recently, she worked on an integrated electro-optic spectrometer and on random quasi-phase matching phenomena in complex assemblies of nanocrystals.
