- Patents for licensing
Summary of the technology
A new technology for producing flat optical components based on optical metasurfaces. These components can potentially serve high resolution imaging, spectrometry, light processing and beam shaping devices. The optical metasurfaces that we develop are composed of closely spaced optical nanoantennas which can be deposited on a wide variety of rigid and flexible surfaces. The engineered nanoantennas allow capturing and directing light at specific colors and polarizations and by that create surfaces with engineered and ‘unnatural’ optical functionality.
The active area of the component can be ultrathin allowing in addition to the unique optical properties to reduce the size of the optical components. Moreover, functionality can be enhanced by creating multilayered components.
Applications
The proposed technology can be used to generate a wide variety of novel diffractive optical elements including flat lenses with multispectral and polarization dependent functionality, multifocal components, beam shapers etc. So far we have demonstrated in the lab the use of this technology to correct chromatic aberrations from a diffractive lens and to generate multifunctional laser beam shapers.

About Yeda
Yeda ("Knowledge" in Hebrew) Research and Development Company Ltd. is the commercial arm of the Weizmann Institute of Science (WIS) and is the second company of its kind established in the world.
WIS is one of the world’s leading multidisciplinary basic research institutions in the natural and exact sciences. It is located in Rehovot, Israel, just south of Tel Aviv. It was initially established as the Daniel Sieff Institute in 1934, by Israel and Rebecca Sieff of London in memory of their son Daniel. In 1949, it was renamed for Dr. Chaim Weizmann, the first President of the State of Israel and Founder of the Institute.
Yeda initiates and promotes the transfer to the global marketplace of research findings and innovative technologies developed by WIS scientists. Yeda holds an exclusive agreement with WIS to market and commercialize its intellectual property and generate income to support further research and education.
Since 1959 Yeda has generated the highest income per researcher compared to any other TTO worldwide. Weizmann has generated a number of groundbreaking therapies, such as Copaxone, Rebif, Tookad, Erbitux, Vectibix, Protrazza, Humira, and recently the CAR-T cancer therapy Yescarta.
Yeda performs the following activities:
◣ Identifies and assesses research projects with commercial potential.
