Title: "Integrated interference wedged structures as a basis for creating of compact light beam splitters with improved parameters"
Keywords: integrated interference wedged structure, light beam splitter
Abstract: On the base to combine in one plane and in a puzzle type of properly designed parts of planar, sheet-like, Interference Wedged Structures, including Composed Interference Wedged Structure), the possibility for realization of new, integrated light beam splitters (essentially for laser beams) is shown. They have useful competitive properties. The optimized splitters (provided by theoretical treatment) assure smooth splitting in increased linear variation range of the transmission from ~ 80-95% to 5% and reflection in combination with large working range. The low slope of transmission variation permits to split 3-5 mm diameter beams and with focusing - ~15 mm and more. The control is by sliding the splitter in its plane that conserves the direction of the formed beams. No polarization requirements and the work is possible for high power laser beams. Convenient practical realization is the use of the mask technology for integrated circuits for sequential deposition of necessary layers.
