Gratings and Planar Wave Guides

5” wafer processing of sub-micron grating structures with various grating periods. Full face gratings as well as partial structuring are feasible. Customized optical designs along with superior grating profiles ensure high performing products.

Sub-micron diffractive structures and high index coatings.
Planar waveguides (PWG) consist of sub-micron grating structures and coatings with high refractive index. Optics Balzers manufactures gratings with high uniformity across extended areas, as well as the coatings for waveguides that comply with low defect standards. Optimized coupling of light into waveguides can be supported by design assist service.
