Design specification and development of test procedures for diverse optical components. Statistical quality control of fabrication processes on the assembly line.

a. Past research was all within the MSc-PhD framework at the Hebrew University. Investigation of the dielectric properties of ferroelectric crystals. The purpose of the research was to find the inherent switching limits of the material and to propose suggestions for achieving performance close to these limits.

b. Current Research and Development activities are focused on theoretical developments in the area of glass forming liquids. An important and currently overlooked feature has been identified. I am now collaborating with researchers at the Hebrew University in order to explore the implications and meaning of this feature. Preliminary results were presented in Wisla last year, and I am now working on a paper in this area.

c. Future Directions for Research and Development -During the last few month I have undergone training and have become familiar with the laboratory of Prof. Salman Noach. I shall be joining the research activities of the lab and intend to lead a research project dealing with Optoelectronic devices based on nano-photonic structures incorporated in electro-optic crystals during their growth, designed for active Q switching, and electric tunable wavelength, and coupling in solid state laser systems.
