Synthesis and applications of
3D nanostructures and 3D light waves

Seminar by
Prof. Rafael Piestun
University of Colorado, Boulder

Abstract: The first part of this talk describes recent developments in fabrication processes for 3D photonic structures using top-down and bottom-up techniques. In particular, it describes innovations in the use of ultrafast laser micromachining in combination with other unconventional techniques that enable applications such as 3D diffractive optics and scalable photonic crystals.
The second part of the talk deals with approaches for tailoring the 3D response of an optical system. 3D responses are used for processing information at the sensor level and to enhance the overall performance of task specific imaging systems.

Bio: Rafael Piestun received the degree of Ingeniero Electricista from the Universidad de la Republica (Uruguay) and the MSc. and Ph.D. degrees in Electrical Engineering from the Technion - Israel Institute of Technology. He worked for two years as a postdoctoral researcher at Stanford University. Since 2001 he has been an Assistant Professor in the Department of Electrical and Computer Engineering and the Department of Physics at the University of Colorado - Boulder. He was a Fulbright scholar, an Eshkol fellow, and received the Minerva, El-Op, and Gutwirth prizes. He served in the editorial committee of Optics and Photonics News and is currently a topical editor of Applied Optics. His areas of interest include nano-photonics, ultrafast optics, inverse problems, and imaging.
