We have research programs broadly spanning the area of optics of structured materials and structuring at micro-/nano- lengthscales. For our
publications and results in these areas, please visit the publications webpage
Another good way to get an idea of the research in our group would be to look at the Ph.D. theses that have been written by our students.
These theses can be found at the Theses webpage
I have begun to write out a few things and hope to get things up soon. Right now consider this page to be under CONSTRUCTION
Multi-photon absorption laser microwriter We have developed a multi-photon based laser writer with less than 0.5 micrometer dot and line resolution and writing speeds of 2 mm/s using a laser giving
subnanosecond pulses at 532 nm. We utilize commercial photoresist and two-photon absorber molecule mixes to achieve with a sub-nanosecond laser this effect that is typically done with very expensive femtosecond lasers.
Surface plasmon enhanced spectroscopy: We have studied the enhancement of both Raman scattering (SERS) and fluorescence (SEF) due to surface plasmons on corrugated gratings. This poster gives a sample of our work in this direction.
Sculptured thin films and their patterning Using oblique angle deposition methods for columnar growth and in-situ substrate motion,
a variety of structured thin films in the form of obliquely oriented columns, helices, spheroidal structures etc. can be grown. These methods can be combined with pre-patterned substrates to result in structured films with a two-scale structure.
