Semester/Master projects

  •  Tomography of micro and nano-objects

We are looking for a motivated master student interested in the fields of microengineering, microfluidics, and optics to work on a multidisciplinary project as his/her master thesis. The goal is to fabricate a microcavity with inclined reflecting walls where a sample is put for recording images from multiple views. These images are then utilized in computational algorithms for 3D reconstruction of the sample. This platform and technique will be finally used for tomography of biological samples such as cells and other microorganisms.

The main challenge in the fabrication of this microcavity is to get surfaces with optical quality, i.e. the surface roughness of few 10s of nanometers. A SEM picture of a fabricated sample can be seen below:

  • Microfabrication of SU-8 optical waveguides

The Laboratory of Optics is looking for motivated master students interested in developing semester projects on optical waveguides. Among various methods to fabricate waveguides, SU-8 is a popular material since it has a simple fabrication process and can be easily integrated into the micro-devices. The goal of this project is to fabricate SU-8 waveguides for imaging micro-sized features on the device. If interested, please contact Pooria Hadikhani (pooria.hadikhani@epfl.ch).

  • Information retrieval through scattering media (noisy channels)
Solid background in experimental or nonlinear optics mandatory. Possibilities to apply techniques developed within the lab in several different types of scattering media ranging from biological tissues to optical fibers.
  • Optofluidic devices for energy applications
Primary scope deals with the development of microfluidic devices in PDMS for solar thermal devices.
  • Hollow plasmonic nanoshells
Student will characterize vapor generation and catalytic properties of hollow plasmonic nanoshells.
  • Leaf optofluidics
Chloroplasts are optically sensitive cells. They will be manipulated to generate a variety of optofluidic devices.
  • Optofluidics for solar plasmonic-photocatalysis

Ranges in scope from characterizing and developing a solar simulator using LEDs and/or supercontiuum laser as well as testing solar plasmonic-photocatalytic fuel microfluidic chips.

 

Interested students are encouraged to e-mail info.lo@epfl.ch  and Prof. Psaltis (demetri.psaltis@epfl.ch) with the subject title “Semester/Master Project”. For non-EPFL students, please attach your CV and a website containing your information along with a brief research proposal.
 
Masters students are strongly encouraged to apply for EPFL Excellence Fellowships.
