Journal ArticleDOI
Ultraviolet-emitting ZnO nanowires synthesized by a physical vapor deposition approach
TL;DR: In this article, the unidirectional growth of the ZnO nanowires was controlled by the conventional vapor-liquid solid mechanism, and the observed room temperature UV emission was ascribed to the decrease in structure defects as compared to bulk materials.
Journal ArticleDOI
Ultrafast All-Optical Graphene Modulator
Wei Li,Bigeng Chen,Chao Meng,Wei Fang,Yao Xiao,Xiyuan Li,Zhifang Hu,Yingxin Xu,Limin Tong,Hongqing Wang,Wei-Tao Liu,Jiming Bao,Y. Ron Shen,Y. Ron Shen +13 more
TL;DR: It is shown that a graphene-clad microfiber all-optical modulator can achieve a modulation depth of 38% and a response time of ∼ 2.2 ps, limited only by the intrinsic carrier relaxation time of graphene.
Journal ArticleDOI
Fabrication of high-Q lithium niobate microresonators using femtosecond laser micromachining
Jintian Lin,Yingxin Xu,Zhiwei Fang,Min Wang,Jiangxin Song,Nengwen Wang,Lingling Qiao,Wei Fang,Ya Cheng +8 more
TL;DR: In this paper, a high-Q lithium niobate (LN) whispering gallery mode (WGM) microresonators suspended on silica pedestals were fabricated by femtosecond laser direct writing followed by focused ion beam (FIB) milling.
Journal ArticleDOI
Creating polarization-entangled photon pairs from a semiconductor quantum dot using the optical Stark effect.
TL;DR: This work uses an external field, here a continuous-wave laser tuned to the QD in the ac Stark limit, to cancel the splitting and create two-photon entanglement, and shows that polarization-entangled photons can be routinely produced in semiconductor nanostructures.
Journal ArticleDOI
Random lasing in weakly scattering systems
Xiaohua Wu,Wei Fang,Alexey Yamilov,Alexey Yamilov,Andrey A. Chabanov,Andrey A. Chabanov,Ara A. Asatryan,Lindsay C. Botten,Hui Cao +8 more
TL;DR: In this paper, a detailed experimental and numerical study of random lasing in weakly scattering systems is presented, where the interference of scattered light, which is weak in the passive systems, is greatly enhanced in the presence of high gain, providing coherent and resonant feedback for lasing.
