15 April 1993 Waveguide Fresnel lenses with curved diopters: a BPM analysis
Author Affiliations +
The beam propagation method (BPM) is used to assess the performance of a waveguide Fresnel lens with given parameters (f# equals 4.6, (delta) n equals 0.08221 at (lambda) equals 830 nm) as a function of the support curve (i.e., of the front diopter of the lens). It is shown that the lenses having circular and parabolic front diopters (which almost coincide in the paraxial approximation) are corrected from third-order aberrations over a field of view of several degrees, wide enough to confirm the suitability of these lenses for integrated optical signal processing applications. The convenience of correcting its chromatic aberration is also discussed.
