| 1 | Ultra-compact broadband polarization beam splitter with strong expansibility显示文摘Based on the traditional directional coupler, we proposed a scheme to design on-chip polarization beam splitters using an inverse design method. In our scheme, the coupling area of the designed devices are only 0.48 μm× 6.4 μm. By manipulating the refractive index of the coupling region, the devices can work in C-band,L-band, O-band, or any other communication band. Different from conventional design methods, which need to adjust the design parameters artificially, if the initial conditions are determined, the proposed scheme can automatically adjust the design parameters of devices according to specific requirements. The simulation results show that the insertion losses of the designed polarization beam splitters can be less than 0.4 dB(0.35 dB) for TE(TM)mode at the wavelengths of 1310, 1550, and 1600 nm, and the extinction ratios are larger than 19.9 dB for the TE and TM modes at all three wavelengths. Besides, the extinction ratios of both polarization states are more than 14.5 dB within the wavelength range of 1286–1364 nm, 1497–1568 nm, and 1553–1634 nm. At the same time,the insertion losses are smaller than 0.46 dB. | JIE HUANG JUNBO YANG DINGBO CHEN XIN HE YUNXIN HAN JINGJING ZHANG ZHAOJIAN ZHANG | 2018 | Photonics Research2018，6，6： | 3 |

| 4 | Unique and complementary suppression of cGAS-STING and RNA sensing- triggered innate immune responses by SARS-CoV-2 proteins显示文摘The emergence of SARS-CoV-2 has resulted in the COVID-19 pandemic,leading to millions of infections and hundreds of thousands of human deaths.The efficient replication and population spread of SARS-CoV-2 indicates an effective evasion of human innate immune responses,although the viral proteins responsible for this immune evasion are not clear.In this study,we identified SARS-CoV-2 structural proteins,accessory proteins,and the main viral protease as potent inhibitors of host innate immune responses of distinct pathways.In particular,the main viral protease was a potent inhibitor of both the RLR and cGAS-STING pathways.Viral accessory protein 0RF3a had the unique ability to inhibit STING,but not the RLR response.On the other hand,structural protein N was a unique RLR inhibitor.0RF3a bound STING in a unique fashion and blocked the nuclear accumulation of p65 to inhibit nuclear factor-KB signaling.3CL of SARS-CoV-2 inhibited K63-ubiquitin modification of STING to disrupt the assembly of the STING functional complex and downstream signaling.Diverse vertebrate STINGs,including those from humans,mice,and chickens,could be inhibited by 0RF3a and 3CL of SARS-CoV-2.The existence of more effective innate immune suppressors in pathogenic coronaviruses may allow them to replicate more efficiently in vivo.Since evasion of host innate immune responses is essential for the survival of all viruses,our study provides insights into the design of therapeutic agents against SARS-CoV-2. | Yajuan Rui Jiaming Su Si Shen Ying Hu Dingbo Huang Wenwen Zheng Meng Lou Yifei Shi Meng Wang Shiqi Chen Na Zhao Qi Dong Yong Cai Rongzhen Xu Shu Zheng Xiao-Fang Yu | 2021 | Signal Transduction and Targeted Therapy2021，6，4： | 1 |
| 5 | A Historic Choice:Democratic Reform in Tibet显示文摘In mid—20th century,Tibet,the largest ethnic minority-ruled region in China’s southwest,was still a feudal serfdom under the despotic theocratic rule of officials,lamas and nobles. The Peaceful Liberation of May 1951 freed Tibetans from the fetters of imperialist encroachment to enter a new epoch. | Chen Dingbo | 2009 | China's Ethnic Groups2009，7，1： | 0 |
| 6 | Polarization-induced photocurrent switching effect in heterojunction photodiodes显示文摘The unipolar photocurrent in conventional photodiodes(PDs)based on photovoltaic effect limits the output modes and potential versatility of these devices in photodetection.Bipolar photodiodes with photocurrent switching are emerging as a promising solution for obtaining photoelectric devices with unique and attractive functions,such as optical logic operation.Here,we design an all-solid-state chip-scale ultraviolet(UV)PD based on a hybrid GaN heterojunction with engineered bipolar polarized electric field.By introducing the polarization-induced photocurrent switching effect,the photocurrent direction can be switched in response to the wavelength of incident light at 0 V bias.In particular,the photocurrent direction exhibits negative when the irradiation wavelength is less than 315 nm,but positive when the wavelength is longer than 315 nm.The device shows a responsivity of up to−6.7 mA/W at 300 nm and 5.3 mA/W at 340 nm,respectively.In particular,three special logic gates in response to different dual UV light inputs are demonstrated via a single bipolar PD,which may be beneficial for future multifunctional UV photonic integrated devices and systems. | Dingbo Chen Yu-Chang Chen Guang Zeng Yu-Chun Li Xiao-Xi Li Dong Li Chao Shen Nan Chi Boon S.Ooi David Wei Zhang Hong-Liang Lu | 2023 | Nano Research2023，16，4： | 0 |
