Broadband THz emitters with sufficient functionality are of great importance to fully realize the impact of these applications. This demand has stimulated the exploration of THz emitters with the capability of complex field manipulation. Here we report on the development of Pancharatnam−Berry phase nonlinear metasurface emitters for broadband and multifunctional THz holography. Two types of metasurface holograms are designed by which scalar holographic imaging and dual-polarization holographic imaging are experimentally demonstrated in a broadband frequency range up to over 2.0 THz. We show that both broadband THz beam generation and multifunctional THz field manipulation can be realized simultaneously. These demonstrations exhibit the significant potential of nonlinear metasurface emitters as efficient THz sources, which may have important applications in THz frequency information processing.  \nKEYWORDS: Pancharatnam−Berry phase, nonlinear metasurfaces, terahertz technology, multifunctional holography  \nL  \nocated between the microwave and infrared spectral regimes, terahertz (THz) waves (0.1−10 THz, 1 THz =  \n300 μm) have attracted great attention due to their unique properties. THz waves are capable of penetrating through many materials such as paper and plastic, while their relatively low photon energies have fewer ionization effects on biological samples. Since the vibrational and rotational transitions of many materials are located in the THz frequency band, THz waves have great application to the field of spectroscopy.1,2 As such, THz waves have been utilized in a wide variety of practical applications such as noninvasive sensing,3−7 stand-off inspection and detection,8,9 and wireless communications. 10−12 Therefore, explorations of THz waves are important for both fundamental science and industrial applications, inspiring the development of novel THz devices with new functionalities. In the area of THz technology, generation and manipulation are two important aspects. In particular, an important goal in this area is to achieve a broadband functionality across a wide THz frequency range. The generation of THz waves has been realized by using different strategies, such as nonlinear crystals based on the optical rectification, 13 photoconductive antennas,14 free electron lasers,15 quantum cascade lasers,16 and spintronic emitters.17 On the other hand, manipulation of the THz fields is mainly implemented by using additional optical elements, including polymer diffractive optical elements, 18 silicon gratings, 19 kirigami modulators,20 and metallic gratings.21 To expand and optimize the applications of THz waves, advanced manipulation methods of THz waves with multiple functionalities need to be explored. However, the inherent absorption of materials in additional optical elements is often a major limitation for practical applications. This is  \nespecially obvious for the higher-frequency range where typical optical elements consisting of silicon and polymers reflect or absorb most of the field intensity.22 Therefore, it is important to develop functional THz emitters with the capability of simultaneously realizing broadband generation and functional manipulation of THz waves. To address this issue, nonlinear  \nplasmonic metasurfaces represent a promising avenue.  \nOptical metasurfaces are quasi-","cbCaibEaxwRQNnJp","https://ap.wps.com/l/cbCaibEaxwRQNnJp","pdf",5546907,"English","# Abstract\n# Background: THz waves and applications\n## THz generation strategies\n## THz field manipulation methods\n# Nonlinear plasmonic metasurfaces and metasurface principles\n## Metasurface control of amplitude, phase, and polarization\n## Nonlinear optical metasurface applications\n# THz regime advances and metasurface approaches\n## Nonlinear conversion efficiency and rectification\n## Phase and polarization control in THz emission","[{\"question\":\"Why are nonlinear plasmonic metasurfaces considered promising for THz emitters?\",\"answer\":\"They offer a functional platform for nonlinear THz wave generation, enabling broadband emission combined with advanced field manipulation while avoiding major absorption limitations of conventional optical elements.\"}]","Broadband Terahertz Holography Using Nonlinear Plasmonic Metasurfaces | PDF",1790687995,23]
