Fast Extended Depth of Focus Meta-Optics for Varifocal Functionality
James E. M. Whitehead, Alan Zhan, Shane Colburn +2
Extended depth of focus (EDOF) optics can enable lower complexity optical imaging systems when compared to active focusing solutions. With existing EDOF optics, however, it is diff…
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…
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…
Inverse design of optical elements based on arrays of dielectric spheres
Alan Zhan, Taylor K. Fryett, Shane Colburn +1
Arrays of wavelength scale scatterers are a promising platform for designing optical elements with a compact footprint. The large number of degrees of freedom in this system allows…
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…
