| 2 | Diffraction-limited imaging with monolayer 2D material-based ultrathin flat lenses显示文摘Ultrathin flat optics allow control of light at the subwavelength scale that is unmatched by traditional refractive optics.To approach the atomically thin limit,the use of 2D materials is an attractive possibility due to their high refractive indices.However,achievement of diffraction-limited focusing and imaging is challenged by their thickness-limited spatial resolution and focusing efficiency.Here we report a universal method to transform 2D monolayers into ultrathin flat lenses.Femtosecond laser direct writing was applied to generate local scattering media inside a monolayer,which overcomes the longstanding challenge of obtaining sufficient phase or amplitude modulation in atomically thin 2D materials.We achieved highly efficient 3D focusing with subwavelength resolution and diffractionlimited imaging.The high focusing performance even allows diffraction-limited imaging at different focal positions with varying magnifications.Our work paves the way for downscaling of optical devices using 2D materials and reports an unprecedented approach for fabricating ultrathin imaging devices. | Han Lin Zai-Quan Xu Guiyuan Cao Yupeng Zhang Jiadong Zhou Ziyu Wang Zhichen Wan Zheng Liu Kian Ping Loh Cheng-Wei Qiu Qiaoliang Bao Baohua Jia | 2020 | Light(Science & Applications)2020，9，1： | 9 |

| 4 | Graphene metalens for particle nanotracking显示文摘Particle nanotracking(PNT)is highly desirable in lab-on-a-chip systems for flexible and convenient multiparameter measurement.An ultrathin flat lens is the preferred imaging device in such a system,with the advantage of high focusing performance and compactness.However,PNT using ultrathin flat lenses has not been demonstrated so far because PNT requires the clear knowledge of the relationship between the object and image in the imaging system.Such a relationship still remains elusive in ultrathin flat lens-based imaging systems because they operate based on diffraction rather than refraction.In this paper,we experimentally reveal the imaging relationship of a graphene metalens using nanohole arrays with micrometer spacing.The distance relationship between the object and image as well as the magnification ratio is acquired with nanometer accuracy.The measured imaging relationship agrees well with the theoretical prediction and is expected to be applicable to other ultrathin flat lenses based on the diffraction principle.By analyzing the high-resolution images from the graphene metalens using the imaging relationship,3D trajectories of particles with high position accuracy in PNT have been achieved.The revealed imaging relationship for metalenses is essential in designing different types of integrated optical systems,including digital cameras,microfluidic devices,virtual reality devices,telescopes,and eyeglasses,and thus will find broad applications. | XUEYAN LI SHIBIAO WEI GUIYUAN CAO HAN LIN YUEJIN ZHAO BAOHUA JIA | 2020 | Photonics Research2020，8，8： | 2 |

| 6 | All-optical logic gates based on hierarchical photonic crystal modulated photoluminescence of perovskite nanocrystals显示文摘Halide perovskites exhibit high performance in all sorts of optoelectronic and photonic areas, suggesting their huge potential in integrated photonic devices. However, until now, all optical logic gates based on perovskites are still rarely explored, hindering the development of all-optical networks and computing. Herein, a new concept of all-optical logic gates is proposed based on the modulation of photoluminescence(PL) from perovskite nanocrystals(PNCs). A hierarchical photonic crystal(Hie PhC) is developed by self-assembling polystyrene(PS) and SiO2nanoparticles, which exhibit a higher PL enhancement than that of a monolayer PhC. Moreover, the light-controlled PL is realized by taking advantage of the high thermal response of the PL from PNCs/Hie PhC on polyethylene(PE) substrate, assisted by a graphene layer for light-heat conversion. Consequently, optical diode and triode are achieved based on the modulated PL, which exhibit contrast ratios(CR) of 24.7 and 74.0 dB, respectively.All-optical logic gates, including “AND”, “OR” and “NOT”, are realized based on the optical diode and triode. | WANG Yun ZHA YanFang YANG YunYi LIU CiHui DI YunSong CAO GuiYuan WEI ShiBiao CHEN ZhiHui GAN ZhiXing | 2023 | Science China(Technological Sciences)2023，66，9： | 0 |
| 7 | High tolerance detour-phase graphene-oxide flat lens显示文摘Flat lenses thinner than a wavelength promise to replace conventional refractive lenses in miniaturized optical systems.However,Fresnel zone plate flat lens designs require dense annuli,which significantly challenges nanofabrication resolution.Herein,we propose a new implementation of detour phase graphene flat lens with flexible annular number and width.Several graphene metalenses demonstrated that with a flexible selection of the line density and width,the metalenses can achieve the same focal length without significant distortions.This will significantly weaken the requirement of the nanofabrication system which is important for the development of large-scale flat lenses in industry applications. | SHIBIAO WEI GUIYUAN CAO HAN LIN HAORAN MU WENBO LIU XIAOCONG YUAN MICHAEL SOMEKH BAOHUA JIA | 2021 | Photonics Research2021，9，12： | 0 |
| 8 | Broadband Diffractive Graphene Orbital Angular Momentum Metalens by Laser Nanoprinting显示文摘Optical beams carrying orbital angular momentum(OAM)play an important role in micro-/nanoparticle manipulation and information multiplexing in optical communications.Conventional OAM generation setups require bulky optical elements and are unsuitable for on-chip integration.OAM generators based on metasurfaces can achieve ultracompact designs.However,they generally have limited working bandwidth and require complex designs and multistep time-consuming fabrication processes.In comparison,graphene metalenses based on the diffraction principle have simple designs and can be fabricated by laser nanoprinting in a single step.Here,we demonstrate that a single ultrathin(200 nm)graphene OAM metalens can integrate OAM generation and high-resolution focusing functions in a broad bandwidth,covering the entire visible wavelength region.Broadband graphene OAM metalenses with flexibly controlled topological charges are analytically designed using the detour phase method considering the dispersionless feature of the graphene material and fabricated using ultrafast laser nanoprinting.The experimental results agree well with the theoretical predictions,which demonstrate the accuracy of the design method.The broadband graphene OAM metalenses can find broad applications in miniaturized and integrated photonic devices enabled by OAM beams. | Guiyuan Cao Han Lin Baohua Jia | 2023 | Ultrafast Science2023，3，3： | 0 |
