An integrated way to generate and manipulate higher-order Poincaré sphere beams (HOPBs) is a sought-after goal in photonic circuits for high-capacity communication systems. Here, we demonstrate novel method on-chip generation manipulation of HOPBs through combining metasurface with optical waveguides on lithium niobate insulator platform. With phase modulation by diatomic geometric metasurface, guided waves are extracted into free space high signal-to-noise ratio the form two orthogonal circularly polarized vortices which linearly superposed HOPBs. Meanwhile, dual-port waveguide crossing established reconfigure output states an arbitrary point based in-plane interference waves. Our approach provides promising solution compact manner, would be further enhanced employing electro-optical access fully tunable scheme.

Photonic devices rarely provide both elaborate spatial control and sharp spectral over an incoming wavefront. In optical metasurfaces, for example, the localized modes of individual meta-units govern wavefront shape a broad bandwidth, while nonlocal lattice extended many unit cells support high quality-factor resonances. Here, we experimentally demonstrate dielectric metasurfaces in near-infrared that offer light, realizing metalenses focusing light exclusively narrowband resonance leaving off-resonant frequencies unaffected. Our attain this functionality by supporting quasi-bound state continuum encoded with spatially varying geometric phase. We leverage capability to realize versatile platform multispectral shaping where stack each multiple independently controlled states continuum, molds distinctively at wavelengths yet stay transparent rest spectrum. Such is scalable visible applications augmented reality displays.

The combination of conventional polarization optical elements, such as linear polarizers and waveplates, is widely adopted to tailor light's state (SOP). Meanwhile, less attention has been given the manipulation degree (DOP). Here, we propose metasurface-based that can filter unpolarized incident light with any prescribed SOP DOP, corresponding arbitrary points located both at surface within solid Poincaré sphere. Jones matrix elements metasurface are inverse-designed via adjoint method. As prototypes, experimentally demonstrated in near-infrared frequencies convert into linear, elliptical, or circular polarizations varying DOPs 1, 0.7, 0.4, respectively. Our Letter unlocks a new freedom for optics may break ground variety DOP-related applications, calibration quantum tomography.
