Multipole-phase beams: a new paradigm for structured waves
摘要:
结构波的控制最近在辐射传播和光-物质相互作用的角度打开了创新的场景。特别是,定制的电磁场的传输被调查的电信,除了传统的,几乎饱和的,分割复用技术的目的是探索新的调制格式。携带扭曲波前的光束长期以来被认为是有希望的候选者,然而它们的相位奇异性和有效的复用仍然提出了公开的问题。在一个更一般的洞察结构相位光束,我们在这里介绍和开发一个新的和独特的范例的基础上传输的光束与谐波相位具有多极结构。概述的框架包括多路复用,传输和解复用作为一个整体的第一次,描述波场演化的共形映射,并直接解决以前的解决方案的关键问题。由于它的潜力,多功能性和易于实施,我们希望这种全新的模式,特别是在自由空间,从光学到微波和无线电制度的空分复用找到广泛的应用。
英文摘要:
The control of structured waves has recently opened innovative scenarios in the perspective of radiation propagation and light-matter interaction. In particular, the transmission of customized electromagnetic fields is investigated for telecommunications, with the aim of exploring new modulation formats besides the traditional, almost saturated, division multiplexing techniques. Beams carrying twisted wavefronts have long been recognized as the promising candidates, however their phase singularities and efficient multiplexing still raise open issues. In a more general insight into structured-phase beams, we introduce and develop here a new and unique paradigm based on the transmission of beams with harmonic phases having a multipole structure. The outlined framework encompasses multiplexing, transmission, and demultiplexing as a whole for the first time, describing wavefields evolution in terms of conformal mappings, and solving straightforwardly the critical issues of previous solutions. Because of its potentialities, versatility, and ease of implementation, we expect this completely new paradigm to find widespread applications for space division multiplexing especially in free space, from the optical to the microwave and radio regimes.
