摘要：
A synthesis algorithm is presented for wide-field diffractive focusing lenses in waveguides. Analytic optimization of the phase transformation is used to widen the angular field, and the efficiency is improved by parametric optimization of the local grating profile. If the effective-index modulation is DELTAn(eff) almost-equal-to 0.1, a curved F:5 singlet in contact with the pupil can achieve a diffraction-limited angular field of approximately +/ 3-degrees, whereas a planar lens in a telecentric configuration can achieve approximately +/- 8-degrees.
