Abstract Ultracompact light emission manipulation is crucial for various applications, including illumination, biosensing, and quantum photonics. Despite significant advancements in lasing manipulation, achieving complex vectorial wavefront control over fluorescence inherently challenging due to its incoherent, omnidirectional, unpolarized, phase‐random characteristics. Here, the light‐emitting metasurfaces (LEMs), equipped with amplitude encoding capabilities, are introduced realize unidirectional incoherent photoluminescence (PL) holography. Through engineering interaction between LEM guided PL, diffraction angle, linear polarization state, intensity of PL independently controlled. Furthermore, phase capability LEM, combined enhanced spatial coherence experimentally enabled holography alongside polarization‐multiplexed nanoprinting. This versatile platform provides a simplified approach promising multiple potential applications nanophotonics devices.

Abstract Simultaneous and independent control of light's intensity phase remains a critical challenge for multifunctional metasurfaces, as conventional designs suffer from inherent parameter correlations orientation‐dependent limitations. Here, minimalist chiral metasurface platform is proposed, achieving complete decoupling modulation through paradigm‐shifting meta‐atom design. Each unit functions polarization‐sensitive optical rotator, circumventing the orientation degeneracy constraints Malus' law while enabling arbitrary Pancharatnam‐Berry imprinting. This unique mechanism allows single‐layer integration dual functionalities: polarization‐encoded grayscale nanoprinting broadband wavefront shaping (e.g., holography or vortex generation). Experimental demonstrations validate non‐interfering operation both functionalities within unified architecture. The design paradigm provides scalable route toward ultra‐compact devices augmented reality displays anti‐counterfeiting applications, significantly advancing frontier meta‐optics.
