| 1 | Milliwatt terahertz harmonic generation from topological insulator metamaterials显示文摘Achieving effcient,high-power harmonic generation in the terahertz spectral domain has technological applications,for example,in sixth generation(6G)communication networks.Massless Dirac fermions possess extremely large terahertz nonlinear susceptibilities and harmonic conversion effciencies.However,the observed maximum generated harmonic power is limited,because of saturation effects at increasing incident powers,as shown recently for graphene.Here,we demonstrate room-temperature terahertz harmonic generation in a Bi_(2)Se_(3) topological insulator and topological-insulator-grating metamaterial structures with surface-selective terahertz field enhancement.We obtain a third-harmonic power approaching the miliwatt range for an incident power of 75 mW-an improvement by two orders of magnitude compared to a benchmarked graphene sample.We establish a framework in which this exceptional performance is the result of thermodynamic harmonic generation by the massless topological surface states,benefiting from ultrafast dissipation of electronic heat via surface-bulk Coulomb interactions.These results are an important step towards on-chip terahertz(opto)electronic applications. | Klaas-Jan Tielrooij Alessandro Principi David Saleta Reig Alexander Block Sebin Varghese Steffen Schreyeck Karl Brunner Grzegorz Karczewski Igor Ilyakov Oleksiy Ponomaryov Thales V.A.G.de Oliveira Min Chen Jan-Christoph Deinert Carmen Gomez Carbonell Sergio O.Valenzuela Laurens W.Molenkamp Tobias Kiessling Georgy V.Astakhov Sergey Kovalev | 2022 | Light(Science & Applications)2022，11，11： | 2 |

| 18 | A universal route to efficient non-linear response via Thomson scattering in linear solids显示文摘Non-linear materials are cornerstones of modern optics and electronics.Strong dependence on the intrinsic properties of particular materials,however,inhibits the at-will extension of demanding non-linear effects,especially those second-order ones,to widely adopted centrosymmetric materials(for example,silicon)and te chnologically important burgeoning spectral domains(for example,terahertz frequencies).Here we introduce a universal route to efficient non-linear responses enabled by exciting non-linear Thomson scattering,a fundamental process in electrodynamics that was known to occur only in relativistic electrons in metamaterial composed of linear materials.Such a mechanism modulates the trajectory of charges,either intrinsically or extrinsically provided in solids,at twice the driving frequency,allowing second-harmonic generation at terahertz frequencies on crystalline silicon with extremely large non-linear susceptibility in our proof-of-concept experiments.By offering a substantially material-and frequency-independent platform,our approach opens new possibilities in the fields of on-demand non-linear optics,terahertz sources,strong field light-solid interactions and integrated photonic circuits. | Yongzheng Wen Flavio Giorgianni Igor Ilyakov Baogang Quan Sergey Kovalev Chen Wang Carlo Vicario Jan-Christoph Deinert Xiaoyu Xiong Joe Bailey Min Chen Alexey Ponomaryov Nilesh Awari Andrea Rovere Jingbo Sun Roberto Morandotti Luca Razzari Gabriel Aeppli Junjie Li Ji Zhou | 2023 | National Science Review2023，10，7： | 0 |
