By illuminating an array of nano C-apertures, particles of dimensions less than 100 nm can be transported using optical tweezers at least 10x smaller than currently used. This allows us to move objects on a lab-on-a-chip with unprecedented accuracy for testing and evaluation at different observation regions.

Optimization techniques for solving MAxwell's equations
Curently Maxwell's equations can only be solved in a forward manner using FDTD techniques, severely limiting the ability to design and optimize new nano-photonics structures. We have developed an adjoint optimization technique for solving Maxwell's equations that allows us to design and optimize complex nano structures in a fraction of the time it would take to do this with a forward technique, and leading to better optimized designs.
Ultra-small optically induced electron sources for lithography and inspection
Using highly efficient resonant near-field transducers we create intense optical spots with a diameter less than 15 nm. By using 257 nm light we can create bright electron beams by irradiating CeBr. Emphasis is placed on creating an array of electron beams using repeatable and highly accurate CMOS compatible fabrication techniques. Funded by DARPA
Photo-thermal sustainable energy conversion
We investigate novel energy conversion schemes using photo-thermally induced energy generation. The project focuses on total system solutions with very high system conversion efficiencies.
3-D imaging
This project aims at creating 3-D free-floating images that can be seen without the need for glasses as is required for stereoscopic viewing. Novel designs are being evaluated and tested under practical conditions.
