Increasing efficiency of high numerical aperture metasurfaces using the grating averaging technique
Amir Arbabi, Ehsan Arbabi, Mahdad Mansouree +4
One of the important advantages of optical metasurfaces over conventional diffractive optical elements is their capability to efficiently deflect light by large angles. However, me…
MEMS-tunable dielectric metasurface lens
Ehsan Arbabi, Amir Arbabi, Seyedeh Mahsa Kamali +3
Varifocal lenses, conventionally implemented by changing the axial distance between multiple optical elements, have a wide range of applications in imaging and optical beam scannin…
Angle-multiplexed metasurfaces: encoding independent wavefronts in a single metasurface under different illumination angles
Seyedeh Mahsa Kamali, Ehsan Arbabi, Amir Arbabi +3
The angular response of thin diffractive optical elements is highly correlated. For example, the angles of incidence and diffraction of a grating are locked through the grating mom…
Complex wavefront engineering with disorder-engineered metasurfaces
Mooseok Jang, Yu Horie, Atsushi Shibukawa +7
Recently, complex wavefront engineering with disordered media has demonstrated optical manipulation capabilities beyond those of conventional optics. These capabilities include ext…
Controlling the sign of chromatic dispersion in diffractive optics with dielectric metasurfaces
Ehsan Arbabi, Amir Arbabi, Seyedeh Mahsa Kamali +2
Diffraction gratings disperse light in a rainbow of colors with the opposite order than refractive prisms, a phenomenon known as negative dispersion. While refractive dispersion ca…

Miniature optical planar camera based on a wide-angle metasurface doublet corrected for monochromatic aberrations
Amir Arbabi, Ehsan Arbabi, Seyedeh Mahsa Kamali +3
Optical metasurfaces are two-dimensional arrays of nano-scatterers that modify optical wavefronts at subwavelength spatial resolution. They are poised to revolutionize optics by en…
Multiwavelength polarization insensitive lenses based on dielectric metasurfaces with meta-molecules
Ehsan Arbabi, Amir Arbabi, Seyedeh Mahsa Kamali +2
Metasurfaces are nano-structured devices composed of arrays of subwavelength scatterers (or meta-atoms) that manipulate the wavefront, polarization, or intensity of light. Like oth…
Efficient Dielectric Metasurface Collimating Lenses for Mid-Infrared Quantum Cascade Lasers
Amir Arbabi, Ryan M. Briggs, Yu Horie +2
Light emitted from single-mode semiconductor lasers generally has large divergence angles, and high numerical aperture lenses are required for beam collimation. Visible and near in…
Decoupling optical function and geometrical form using conformal flexible dielectric metasurfaces
Seyedeh Mahsa Kamali, Amir Arbabi, Ehsan Arbabi +2
Physical geometry and optical properties of objects are correlated: cylinders focus light to a line, spheres to a point, and arbitrarily shaped objects introduce optical aberration…
Dielectric Metasurfaces for Complete Control of Phase and Polarization with Subwavelength Spatial Resolution and High Transmission
Amir Arbabi, Yu Horie, Mahmood Bagheri +1
Metasurfaces are planar structures that locally modify the polarization, phase, and amplitude of light in reflection or transmission, thus enabling lithographically patterned flat…
