Journal ArticleDOI
Observation of Third-order Nonlinearities in Graphene Oxide Film at Telecommunication Wavelengths
Xiaochuan Xu,Xiaorui Zheng,Feng He,Zheng Wang,Harish Subbaraman,Yaguo Wang,Baohua Jia,Ray T. Chen +7 more
TL;DR: The observation of ultrahigh third-order nonlinearity about 0.45 cm2/GW in graphene oxide thin films at the telecommunication wavelength region, which is four orders of magnitude higher than that of single crystalline silicon, can potentially significantly advance the performance of all-optical switches.
Journal ArticleDOI
Silicon microdisk-based full adders for optical computing
TL;DR: A ripple-carry electro-optic 2-bit full adder uses microdisks and uses light to carry signals from one bit to the next with high bandwidth and low power consumption per bit, paving the way for future high-speed optical computing systems in the post-Moore's law era.
Journal ArticleDOI
High quality factor subwavelength grating waveguide micro-ring resonator based on trapezoidal silicon pillars.
TL;DR: It is found that an asymmetric effective refractive index profile created by trapezoidal silicon pillars can significantly reduce the bend loss and therefore increase the quality factors of SWGMRs.
Journal ArticleDOI
Silicon on-chip bandpass filters for the multiplexing of high sensitivity photonic crystal microcavity biosensors
Hai Yan,Yi Zou,Swapnajit Chakravarty,Chun-Ju Yang,Zheng Wang,Naimei Tang,Donglei Fan,Ray T. Chen +7 more
TL;DR: With proper engineering of the passband, multiple high sensitivity PC microcavity sensors can be integrated into microarrays and be interrogated simultaneously between a single input and a single output port.
Journal ArticleDOI
Surface ligand-mediated isolated growth of Pt on Pd nanocubes for enhanced hydrogen evolution activity
Fumin Ren,Haiyuan Lu,Haiyuan Lu,Haiyuan Lu,Haotian Liu,Haotian Liu,Zheng Wang,Zheng Wang,Zheng Wang,Yuen Wu,Yuen Wu,Yadong Li,Yadong Li +12 more
TL;DR: Isolated growth of Pt on Pd can be achieved facilely by tuning the coordination interaction between Br− and Pd atoms as discussed by the authors, and the island growth mode Pd@Pt core-shell structure exhibits enhanced catalytic performance compared to that of layered growth mode in the Hydrogen Evolution Reaction.
