Free-space-coupled wavelength-scale disk resonators
Babak Mirzapourbeinekalaye, Sarath Samudrala, Mahdad Mansouree +2
Optical microresonators with low quality factor () can be efficiently excited by and scatter freely propagating optical waves, but those with high typically cannot. Here, we…

Large-scale parameterized metasurface design using adjoint optimization
Mahdad Mansouree, Andrew McClung, Sarath Samudrala +1
Optical metasurfaces are planar arrangements of subwavelength meta-atoms that implement a wide range of transformations on incident light. The design of efficient metasurfaces requ…

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…
