Abstract

For the purpose of design and fabrication, diffraction efficiencies of the trapeziform phase gratings are deduced and compared with rectangular gratings. The parameter design of the grating for high density optical disk storage are presented. Influences of fabrication errors including random errors and system errors are deduced and analyzed.
