Journal ArticleDOI
Versatile fabrication of intact three-dimensional metallic butterfly wing scales with hierarchical sub-micrometer structures.
TL;DR: This work has shown that direct replication from hierarchical structures of various natural species is a promising route to create metallic structures through physical vapor deposi-tion (PVD) of metals.
Journal ArticleDOI
High-Density Hotspots Engineered by Naturally Piled-Up Subwavelength Structures in Three-Dimensional Copper Butterfly Wing Scales for Surface-Enhanced Raman Scattering Detection
Yongwen Tan,Jiajun Gu,Linhua Xu,Xining Zang,Dingxin Liu,Wang Zhang,Qinglei Liu,Shenmin Zhu,Huilan Su,Chuanliang Feng,Genlian Fan,Di Zhang +11 more
TL;DR: In this article, the 3D sub-micrometer Cu structures replicated from butterfly wing scales are successfully tuned by modifying the Cu deposition time, which yields replicas with the best conformal morphologies of original wing scales and in turn the best SERS performance.
Journal ArticleDOI
Four-wave mixing parametric oscillation and frequency comb generation at visible wavelengths in a silica microbubble resonator.
Yong Yang,Xue-Feng Jiang,Sho Kasumie,Guangming Zhao,Linhua Xu,Jonathan M. Ward,Lan Yang,Síle Nic Chormaic +7 more
TL;DR: Dispersion engineering in a microbubble resonator (MBR) fabricated by a two-CO2 laser beam technique is demonstrated, and a frequency comb with 14 comb lines is generated at visible wavelengths.
Journal ArticleDOI
Raman lasing and Fano lineshapes in a packaged fiber-coupled whispering-gallery-mode microresonator
TL;DR: In this article, a whispering gallery mode (WGM) microtoroid resonator embedded in a low refractive index polymer matrix together with a tapered fiber coupler is presented.
Journal ArticleDOI
Four-wave mixing parametric oscillation and frequency comb generation at visible wavelengths in a silica microbubble resonator
Yong Yang,Xue-Feng Jiang,Sho Kasumie,Guangming Zhao,Linhua Xu,Jonathan M. Ward,Lan Yang,Síle Nic Chormaic +7 more
TL;DR: In this article, the authors demonstrate dispersion engineering in a microbubble resonator (MBR) fabricated by a two-CO$_2$ laser beam technique, and the zero dispersion wavelength shifts to values shorter than 764 nm, making phase matching possible around 765 nm.
