| 1 | Ultra-broadband on-chip twisted light emitter for optical communications显示文摘On-chip twisted light emitters are essential components of orbital angular momentum(OAM)communication devices1,2.These devices address the growing demand for high-capacity communication systems by providing an additional degree of freedom for wavelength/frequency division multiplexing(WDM/FDM).Although whispering-gallery-mode-enabled OAM emitters have been shown to possess some advantages3–5,such as compactness and phase accuracy,their inherent narrow bandwidths prevent them from being compatible with WDM/FDM techniques.Here,we demonstrate an ultra-broadband multiplexed OAM emitter that utilizes a novel joint path-resonance phase control concept.The emitter has a micron-sized radius and nanometer-sized features.Coaxial OAM beams are emitted across the entire telecommunication band from 1,450 to 1,650 nm.We applied the emitter to an OAM communication with a data rate of 1.2 Tbit/s assisted by 30-channel optical frequency combs(OFCs).The emitter provides a new solution to further increase capacity in the OFC communication scenario. | Zhenwei Xie Ting Lei Fan Li Haodong Qiu Zecen Zhang Hong Wang Changjun Min Luping Du Zhaohui Li Xiaocong Yuan | 2018 | Light(Science & Applications)2018，7，1： | 7 |
| 2 | Broadband on-chip photonic spin Hall element via inverse design显示文摘The photonic spin Hall effect plays an important role in photonic information technologies,especially in on-chip spin Hall devices.However,conventional devices suffer from low efficiency or narrow bandwidth,which prevents their practical application.Here,we introduce a spin Hall device using inverse design to achieve both high efficiency and broadband.Spin-dependent light separation is enabled by a 2.4μm circular device with 100 nm pixels.The photonic spin Hall element is fabricated on a silicon-on-insulator wafer compatible with a standard integrated photonic circuit.The spin light is detected and emitted with an efficiency of up to 22%and 35%,respectively,over a 200 nm bandwidth at optical wavelength. | ZHENWEI XIE TING LEI HAODONG QIU ZECEN ZHANG HONG WANG XIAOCONG YUAN | 2020 | Photonics Research2020，8，2： | 2 |
| 3 | Engineering of Saccharomyces cerevisiae for co-fermentation of glucose and xylose:Current state and perspectives显示文摘The use of non-food lignocellulosic biomass to produce ethanol fits into the strategy of a global circular economy with low dependence on fossil energy resources.Xylose is the second most abundant sugar in lignocellulosic hydrolysate,and its utilization in fermentation is a key issue in making the full use of raw plant materials for ethanol production and reduce production costs.Saccharomyces cerevisiae is the best ethanol producer but the organism is not a native xylose user.In recent years,great efforts have been made in the construction of xy-lose utilizing S.cerevisiae strains by metabolic and evolutionary engineering approaches.In addition,managing global transcriptional regulation works provides an effective means to increase the xylose utilization capacity of recombinant strains.Here we review the common strategies and research advances in the research field in order to facilitate the researches in xylose metabolism and xylose-based fermentation. | Yali Qiu Meiling Wu Haodong Bao Weifeng Liu Yu Shen | 2023 | Engineering Microbiology2023，3，3： | 0 |
