Design and Fabrication of Diffractive Light-Collecting Microoptical Device with 1D and 2D Lamellar Grating Structures
Figure 2
Schematics of the proposed light-collecting device: (a) overall layout: 9 (3 × 3) blocks of optical elements: 4 blocks of 1D lamellar grating structures, 4 blocks of 2D lamellar grating structures, and a single block of nonpatterned element at the center and (b) cross-sectional view: depth of lens and focal length.
