Compact Folded Metasurface Spectrometer
MohammadSadegh Faraji-Dana, Ehsan Arbabi, Amir Arbabi +3
Recent advances in optical metasurfaces enable control of the wavefront, polarization and dispersion of optical waves beyond the capabilities of conventional diffractive optics. An…
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…
