Erez Hasman

Head of Micro and Nanooptics Laboratory, Faculty of Mechanical Engineering and Russell Berrie Nanotechnology Institute,

Technion - Israel Inst. of Technology, Haifa 32000, Israel.

Erez Hasman received the B.Sc. degree (in physics) in 1981 from the Tel Aviv University, the M.Sc. degree in 1985 from the Technion, Haifa, and the Ph.D. in 1992 from Weizmann Institute of Science, Rehovot, Israel. From 1981 to 1986, he was a senior scientist in Rafael company. From 1992 to 1998, he was in the optics industry as the chief physicist of graphic and recognition products line, in Optrotech company, and later as the technology analysis manager and head of physics group in Elop company in Israel. Presently, he is a Professor of optical sciences and head of Micro and Nanooptics Laboratory, Faculty of Mechanical Engineering and Russell Berrie Nanotechnology Institute, Technion - Israel Institute of Technology, Haifa, Israel. Prof. Erez Hasman has a wide experience in physical optics and specifically in nanoscale optics. His group has made significant contributions in the field of nano-photonics and radiative heat transfer from nanostructures, and specifically for developing a new branch in optics spinoptics: The symmetry breaking in nanostructures due to spin-orbit interaction, potentially opens a new avenue for controlling light in nanometer-scale optical devices. His nanooptics laboratory is involved in research of nanoscale structures, surface plasmon polaritons, near-field manipulation, and thermal radiation from nanoscale-structures.

Abstract:
Spin-symmetry breaking in nanoscale structures caused by spin-orbit interaction, leading to a new branch in optics - spinoptics is presented. The spin-based effects offer an unprecedented ability to control light and its polarization state in nanometer-scale optical devices, thereby facilitating a variety of applications related to nano-photonics. The direct observation of optical spin-Hall effect that appears when a wave carrying spin angular momentum (AM) interacts with plasmonic nanostructures is introduced. A plasmonic nanostructure exhibits a crucial role of an AM selection rule in a light-surface plasmon scattering process. A spin-dependent dispersion splitting was obtained in a structure consisting of a coupled thermal antenna array. The observed effects inspire one to investigate other spin-based plasmonic effects and to propose a new generation of optical elements for nano-photonic applications.
