Alan E. Willner,Hao Huang,Yan Yan,Yongxiong Ren,Nisar Ahmed,Guodong Xie,Changjing Bao,Long Li,Yinwen Cao,Zhe Zhao,Jian Wang,Martin P. J. Lavery,Moshe Tur,Siddharth Ramachandran,Andreas F. Molisch,Nima Ashrafi,Solyman Ashrafi +16 more
TL;DR: In this article, the authors review recent progress in OAM beam generation/detection, multiplexing/demultiplexing, and its potential applications in different scenarios including free-space optical communications, fiber-optic communications, and RF communications.
Journal ArticleDOI
High-capacity millimetre-wave communications with orbital angular momentum multiplexing
Yan Yan,Guodong Xie,Martin P. J. Lavery,Hao Huang,Nisar Ahmed,Changjing Bao,Yongxiong Ren,Yinwen Cao,Long Li,Zhe Zhao,Andreas F. Molisch,Moshe Tur,Miles J. Padgett,Alan E. Willner +13 more
TL;DR: This work demonstrates a 32-Gbit’s−1 millimetre-wave link over 2.5 metres with a spectral efficiency of ~16 bit s− 1 Hz−1 using four independent orbital–angular momentum beams on each of two polarizations, and shows an 8-Gbits−1 link containing two orbital angular momentum beams with crosstalk less than −12.5 dB.
Journal ArticleDOI
Performance metrics and design considerations for a free-space optical orbital-angular-momentum-multiplexed communication link
Guodong Xie,Long Li,Yongxiong Ren,Hao Huang,Yan Yan,Nisar Ahmed,Zhe Zhao,Martin P. J. Lavery,Nima Ashrafi,Solyman Ashrafi,Robert Bock,Moshe Tur,Andreas F. Molisch,Alan E. Willner +13 more
TL;DR: In this paper, the trade-offs for different transmitted beam sizes, receiver aperture sizes, and mode spacing of the transmitted OAM beams under given lateral displacements or receiver angular errors were investigated.
Journal ArticleDOI
Metamaterials-based broadband generation of orbital angular momentum carrying vector beams
TL;DR: A simple approach to broadband generation of orbital angular momentum (OAM) carrying vector beams based on compact metamaterials that consists of two concentric rings in a gold film, where each ring is composed of subwavelength rectangular apertures with gradually varied orientation.
Journal ArticleDOI
Experimental characterization of a 400 Gbit/s orbital angular momentum multiplexed free-space optical link over 120 m.
Yongxiong Ren,Zhe Wang,Peicheng Liao,Long Li,Guodong Xie,Hao Huang,Zhe Zhao,Yan Yan,Nisar Ahmed,Asher J. Willner,Martin P. J. Lavery,Nima Ashrafi,Solyman Ashrafi,Robert Bock,Moshe Tur,Ivan B. Djordjevic,Mark A. Neifeld,Alan E. Willner +17 more
TL;DR: Both experimental and simulation results show that power penalties increase rapidly when the displacement increases, and the influence of channel impairments on the received power, intermodal crosstalk among channels, and system power penalties is investigated.
