Eyal co-leads the science & technology group in the Optics & Materials organization (OMST) in the NIF and Photon science Directorate. Before joining OMST, he worked as a computational physicist in NIF system engineering, and before that as a postdoctoral researcher at the California Institute of Technology (in Applied Physics). His main fields of interest are laser optics technology, light-matter interaction, beam propagation in complex media, and optical modeling. Key technologies of interest include: robust and scalable metasurface optics for high power lasers, dynamically tunable metasurfaces for laser beam control, laser processing of optics, photonics devices based on enhanced light-matter interaction.

 

Fields of expertise:

Optical modeling: Full-wave simulations of Maxwell equations, beam propagation method, ray optics, T and S matrix formalism, analytical methods in optics.

Metasurfaces: e.g., led a team developing an all-glass metasurface technology for high power lasers that is durable and scalable. This technology enables broadband anti-refection layers, freeform optical elements, and waveplates.

Laser processing of glass: e.g., leading the working group for R&D of the laser fabrication of damage mitigation (NIF RAM sites).

Laser induced damage: e.g., study of filamentation damage formation in glass, and formation of damage on RAM sites on NIF optics. 

Light propagation: e.g., modeling of the NIF-like laser systems physics (advancing VBL – the code that is used to model NIF beamlines), as well as beam propagation in the atmosphere and in complex media (e.g., solitons in optical fibers, plasmonic waves on metal surfaces)

Nano-photonics: e.g., plasmonic devices (Ph.D. focus), “Resonant guided wave networks” and ITO based light modulators (concepts originated as postdoc at CalTech)
