| 1 | A metasurface-based light-to-microwave transmitter for hybrid wireless communications显示文摘Signal conversion plays an important role in many applications such as communication,sensing,and imaging.Realizing signal conversion between optical and microwave frequencies is a crucial step to construct hybrid communication systems that combine both optical and microwave wireless technologies to achieve better features,which are highly desirable in the future wireless communications.However,such a signal conversion process typically requires a complicated relay to perform multiple operations,which will consume additional hardware/time/energy resources.Here,we report a light-to-microwave transmitter based on the time-varying and programmable metasurface integrated with a high-speed photoelectric detection circuit into a hybrid.Such a transmitter can convert a light intensity signal to two microwave binary frequency shift keying signals by using the dispersion characteristics of the metasurface to implement the frequency division multiplexing.To illustrate the metasurface-based transmitter,a hybrid wireless communication system that allows dual-channel data transmissions in a light-to-microwave link is demonstrated,and the experimental results show that two different videos can be transmitted and received simultaneously and independently.Our metasurface-enabled signal conversion solution may enrich the functionalities of metasurfaces,and could also stimulate new information-oriented applications. | Xin Ge Zhang Ya Lun Sun Bingcheng Zhu Wei Xiang Jiang Qian Yu Han Wei Tian Cheng-Wei Qiu Zaichen Zhang Tie Jun Cui | 2022 | Light(Science & Applications)2022，11，6： | 3 |
| 2 | Defect engineering on all-inorganic perovskite solar cells for high efficiency显示文摘Perovskite solar cells based on organic–inorganic hybrid perovskite materials have become a research hotspot in photovoltaics field due to their outstanding power conversion efficiency (PCE)[1]. Nonetheless, the organic cations are volatile and have rotation freedom, which is not good for photoand thermal-stability of the devices. | Bingcheng Yu Chuantian Zuo Jiangjian Shi Qingbo Meng Liming Ding | 2021 | Journal of Semiconductors2021，42，5： | 2 |

| 4 | Compact electro-optic modulator on lithium niobate显示文摘Fast electro-optic modulators with an ultracompact footprint and low power consumption are always highly desired for optical interconnects.Here we propose and demonstrate a high-performance lithium niobate electro-optic modulator based on a new 2×2 Fabry–Perot cavity.In this structure,the input and reflected beams are separated by introducing asymmetric multimode-waveguide gratings,enabling TE_(0)−TE_(1)mode conversion.The measured results indicate that the fabricated modulator features a low excess loss of∼0.9dB,a high extinction ratio of∼21dB,a compact footprint of∼2120μm^(2),and high modulation speeds of 40 Gbps OOK and 80 Gbps PAM4 signals.The demonstrated modulator is promising for high-speed data transmission and signal processing. | Bingcheng Pan Hongyuan Cao Yishu Huang Zong Wang Kaixuan Chen Huan Li Zejie Yu Daoxin Dai | 2022 | Photonics Research2022，10，3： | 1 |
| 5 | Step-wise CAG@PLys@PDA-Cu^(2+)modification on micropatterned nanofibers for programmed endothelial healing显示文摘Native-like endothelium regeneration is a prerequisite for material-guided small-diameter vascular regeneration.In this study,a novel strategy is proposed to achieve phase-adjusted endothelial healing by step-wise modification of parallel-microgroove-patterned(i.e.,micropatterned)nanofibers with polydopamine-copper ion(PDA-Cu^(2+))complexes,polylysine(PLys)molecules,and Cys-Ala-Gly(CAG)peptides(CAG@PLys@PDA-Cu^(2+)).Using electrospun poly(L-lactide-co-caprolactone)random nanofibers as the demonstrating biomaterial,step-wise modification of CAG@PLys@PDA-Cu^(2+)significantly enhanced substrate wettability and protein adsorption,exhibited an excellent antithrombotic surface and outstanding phase-adjusted capacity of endothelium regeneration involving cell adhesion,endothelial monolayer formation,and the regenerated endothelium maturation.Upon in vivo implantation for segmental replacement of rabbit carotid arteries,CAG@PLys@PDA-Cu^(2+)modified grafts(2 mm inner diameter)with micropatterns on inner surface effectively accelerated native-like endothelium regeneration within 1 week,with less platelet aggregates and inflammatory response compared to those on non-modified grafts.Prolonged observations at 6-and 12-weeks post-implantation demonstrated a positive vascular remodeling with almost fully covered endothelium and mature smooth muscle layer in the modified vascular grafts,accompanied with well-organized extracellular matrix.By contrast,non-modified vascular grafts induced a disorganized tissue formation with a high risk of thrombogenesis.In summary,step-wise modification of CAG@PLys@PDA-Cu^(2+)on micropatterned nanofibers can significantly promote endothelial healing without inflicting thrombosis,thus confirming a novel strategy for developing functional vascular grafts or other blood-contacting materials/devices. | Bingcheng Yi Boya Zhou Zhenfeng Song Lei Yu Wenbo Wang Wei Liu | 2023 | Bioactive Materials2023，，7： | 1 |
