All-Dielectric Meta-optics for High-Efficiency Independent Amplitude and Phase Manipulation
Brian O. Raeker, Hanyu Zheng, You Zhou +3
Metasurfaces, composed of subwavelength scattering elements, have demonstrated remarkable control over the transmitted amplitude, phase, and polarization of light. However, manipul…

Lossless, Complex-Valued Optical Field Control with Compound Metaoptics
Brian O. Raeker, Anthony Grbic
Forming a desired optical field distribution from a given source requires precise spatial control of a field's amplitude and phase. Low-loss metasurfaces that allow extreme phase a…

Compound Metaoptics for Amplitude and Phase Control of Wavefronts
Brian O. Raeker, Anthony Grbic
Metasurfaces allow tailored control over electromagnetic wavefronts. However, due to the local conservation of power flow, a passive, lossless, and reflectionless metasurface is li…
