Inverse Designed Extended Depth of Focus Meta-Optics for Broadband Imaging in the Visible
Elyas Bayati, Raphael Pestourie, Shane Colburn +3
We report an inverse-designed, high numerical aperture (~0.44), extended depth of focus (EDOF) meta-optic, which exhibit a lens-like point spread function (PSF). The EDOF meta-opti…
Design of achromatic augmented reality visors based on composite metasurfaces
Elyas Bayati, Andrew Wolfram, Shane Colburn +2
A compact near-eye visor (NEV) system that can guide light from a display to the eye could transform augmented reality (AR) technology. Unfortunately, existing implementations of s…
Inverse designed metalenses with extended depth of focus
Elyas Bayati, Raphael Pestourie, Shane Colburn +3
Extended depth of focus (EDOF) lenses are important for various applications in computational imaging and microscopy. In addition to enabling novel functionalities, EDOF lenses can…
The role of refractive index in metalens performance
Elyas Bayati, Alan Zhan, Shane Colburn +1
Sub-wavelength diffractive optics, commonly known as metasurfaces, have recently garnered significant attention for their ability to create ultra-thin flat lenses with extremely sh…
