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…
Design and Analysis of Extended Depth of Focus Metalenses for Achromatic Computational Imaging
Luocheng Huang, James Whitehead, Shane Colburn +1
Metasurface optics have demonstrated vast potential for implementing traditional optical components in an ultra-compact and lightweight form factor. Metasurface lenses, also called…
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…
An Optical Frontend for a Convolutional Neural Network
Shane Colburn, Yi Chu, Eli Shlizerman +1
The parallelism of optics and the miniaturization of optical components using nanophotonic structures, such as metasurfaces present a compelling alternative to electronic implement…
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…
