The complete manipulation of Jones matrix phase-channels using metasurfaces brings forth unparalleled possibilities across diverse wavefront modulation applications. Traditionally, achieving independent control over all four usually involves the introduction chirality with multilayer or three-dimensional metasurfaces. Here, we present a general chirality-free method that relies on polarization base transformation planar minimalist metasurface, effectively decoupling phase-channels, thereby unleashing fundamental boundaries imposed by conventional linear circular bases. To achieve these channels, employ an inverse design methodology leveraging gradient descent algorithm. Remarkably, our strategy enables channel modulations only three degrees freedom within meta-structures. As proof-of-concept, experimentally project far-field holographic images, each corresponding to one holding promises for various applications such as augmented/virtual reality display, information encryption, optical communication and data storage.

Abstract Vectorial metasurface holography, allowing for independent control over the amplitude, phase, and polarization distribution of holographic images enabled by metasurfaces, plays a crucial role in realm optical display, optical, quantum communications. However, previous research on vectorial holography has typically been restricted to single degree freedom input channel output, thereby demonstrating very limited modulation capacity. This work presents novel method achieve multi‐channel harnessing spin‐orbit‐locking vortex beams. In each channel, field is encoded with pair total angular momentums (TAMs) featuring two orthogonal spin (SAMs) independently locked arbitrary orbital (OAMs). The methodology relies modified Gerchberg‐Saxton algorithm, enabling encoding various TAM channels within phase profile. Consequently, pure geometry‐phase non‐interleaved approach can be used support such achieving high selectivity both SAM OAM, offering precise routing manipulation complex light channels. paradigm shift promising avenues high‐density information processing future photonic device design.
