The Optical Nanomaterial Laboratory at the Physics Department of ETH Zurich is looking for a PhD student in Nonlinear Photonics for Active Metal-Oxides Metasurfaces.


Project background
The quest of materials with no losses in a broad optical range and high energy conversion efficiencies is still open for the development of new nanotechnologies in optoelectronics and photonics. In our group, we use metal-oxides ferroelectric materials, such as barium titanate or lithium niobate, because of their wide bandgap for a broad transparent window, second-order optical nonlinearities, strong electro-optic effects and high damage threshold.


Job description
This PhD project aims to fabricate miniature optoelectronic devices from barium titanate and lithium niobate thin films or nanoparticles. Most current flat photonic structures are passive, here the goal is to create multifunctional sub-wavelength devices that can be actively tuned without changing the hardware design. The PhD project will also explore further functionalities of metasurfaces to control optical quantum emitters. The project involves the fabrication of metasurfaces by top-down and bottom-up methods, the optical characterization using custom-built setups, numerical modelling and the development of flat photonic devices with nonlinear materials for classical and quantum applications.

Your profile
The successful candidate should be highly motivated and creative, should have a Master's degree in physics, optics, material sciences, or related fields, and be interested in working in an interdisciplinary environment at the interface of nanotechnology, photonics and materials. The preferred starting date is September 2019.

ETH Zurich
ETH Zurich is one of the world's leading universities specialising in science and technology. We are renowned for our excellent education, cutting-edge fundamental research and direct transfer of new knowledge into society. Over 30,000 people from more than 120 countries find our university to be a place that promotes independent thinking and an environment that inspires excellence.
