Breaking the limitation of polarization multiplexing in optical metasurfaces with engineered noise

Bo Xiong et al.

Summary: By introducing engineered noise to the precise solution of Jones matrix elements, we have surpassed the fundamental limit of polarization multiplexing capacity of metasurfaces. Through experiments, we have achieved up to 11 independent holographic images using a single metasurface illuminated by visible light with different polarizations, which is the highest reported capacity for polarization multiplexing. With the combination of position multiplexing, the metasurface is capable of generating 36 distinct images, forming a holographic keyboard pattern. This discovery opens up new possibilities for high-capacity optical display, information encryption, and data storage.

Summary: For photonic devices, disorder and complexity have traditionally been seen as unwanted features. However, this review shows that disorder can actually be harnessed to enable unique functionalities in photonic devices. Disordered systems offer more possibilities and diverse optical responses compared to ordered systems.
