摘要：
Wide-angle far-field line generation using a simple optical system consisting of a cylindrical lens and a resonance-domain diffractive beam-shaping element is proposed. The desired intensity distribution is realized as a local average of the coherent superposition of the component fields in different diffraction orders of a multiple-beam-splitter grating with nanoscale transverse features. Fabrication tolerances of the proposed method are investigated and the system is demonstrated experimentally using electron beam lithography and reactive ion etching. (C) 2000 Elsevier Science B.V.
