Abstract

Grating lenses will have wide applications in optical communication and optical information processing. Utilizing their focusing, imaging and Fourier transforming functions, they are applied, for example, to couplers for fiber optics^1,2), optical heads in optical disk systems³⁾, X-ray imaging elements⁴⁾ and Fourier transforming lenses for optical processors⁵⁾. Applications to waveguide devices^6-8) are also reported.
