Abstract Helicity-multiplexed metasurfaces based on symmetric spin–orbit interactions (SOIs) have practical limits because they cannot provide central-symmetric holographic imaging. Asymmetric SOIs can effectively address such limitations, with several exciting applications in various fields ranging from asymmetric data inscription communications to dual side displays smart mobile devices. Low-loss dielectric materials an excellent platform for realizing exotic phenomena efficiently. In this...

Here, we...
Abstract Symmetric spin–orbit interaction (SOI)‐based approaches apply a practical limit on helicity multiplexed metaoptics, i.e., center symmetric information encoding. Contrarily, asymmetric SOI's based the combination of geometric and propagation phase‐delay can effectively address such limitations for multifunctional metaoptics cost design complexities. In this paper, simple SOI‐based technique is realized employing only single unit cell, breaking conventional tradeoff between complexity...
