FDTD-based Inverse Design enables f/0.27 flat Microlens Array for Integral Imaging

Tina M. Hayward, Robert Stewart, Rajesh Menon +1

We demonstrate a high-NA (0.88), ultra-low-f-number (f/0.2714), multi-wavelength (480nm, 550nm and 650nm) multilevel diffractive MicroLens Array (MLA) using inverse design. Each mi…
