Area of Science:

Optics and Photonics
Metamaterials
Nanotechnology

Background:

Polarization optics is crucial for various optical technologies, but controlling polarization independently of phase and intensity remains a challenge.
Existing methods for polarization manipulation often do not allow for simultaneous control of other light properties.

Purpose of the Study:

To propose and experimentally validate a new paradigm for simultaneous and independent control of light intensity and phase using polarization modulation.
To develop a Malus-metasurface-assisted strategy for designing advanced optical devices.

Main Methods:

Utilized the orientation degeneracy of Malus's law to create a one-to-many mapping for designing anisotropic plasmonic nanostructures.
Engineered the Pancharatnam-Berry phase profile while maintaining continuous intensity modulation.
Experimentally validated the proposed Malus metadevice concept.

Main Results:

Demonstrated simultaneous and independent control over light intensity and phase through polarization modulation.
Successfully generated a near-field greyscale pattern and projected an independent far-field holographic image with an ultrathin metasurface.
Developed a multifunctional nano-optical device by merging phase and amplitude manipulation functionalities.

Conclusions:

The proposed Malus-metasurface paradigm significantly advances conventional polarization optics by enabling multifunctional devices.
This approach offers a pathway to complex optical functionalities without increasing nanostructure complexity.
Potential applications include information multiplexing, encryption, anti-counterfeiting, and advanced displays for augmented and virtual reality.
