Real Time Full-Color Imaging in a Meta-Optical Fiber Endoscope
Johannes E. Froech, Luocheng Huang, Quentin A. A. Tanguy +6
Endoscopes are an important component for the development of minimally invasive surgeries. Their size is one of the most critical aspects, because smaller and less rigid endoscopes…
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…
Design and Optimization of Ellipsoid Scatterer-based Metasurfaces via the Inverse T-Matrix Method
Maksym V. Zhelyeznyakov, Alan Zhan, Arka Majumdar
Large-area metasurfaces composed of discrete wavelength-scale scatterers present an extremely large number of degrees of freedom to engineer an optical element. These degrees of fr…
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…
Varifocal zoom imaging with large area focal length adjustable metalenses
Shane Colburn, Alan Zhan, Arka Majumdar
Varifocal lenses are essential components of dynamic optical systems with applications in photography, mixed reality, and microscopy. Metasurface optics has strong potential for cr…
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…
