Abstract
We study the design of planar micro-grating and propose a new approach to fabricate planar micro-grating. By the basic grating diffractive theory (rigorous coupled wave theory), suitable and optimized structure (within our manufacturing capabilities) of grating for our application is found. The fabrication of planar micro-grating is demonstrated by Laser LIGA technology, using the instrument of KrF (248 nm) excimer laser system. The micro-grating with the continuous smooth profile and the pitch 2.5 μ m is shown.
