Abstract
The purpose of this paper is to celebrate Sir D. Payne’s 80th birthday by dedicating our latest results as a continuation of his work in optical communications. One of the important issues in optical communications is to protect the transmission information data passing through optical fiber channels. Many ideas have been proposed and are being actively developed to implement in the physical layer of ultra-high-speed communications. As a representative example, a methodology that achieves this goal by fusing modulation techniques in ordinary optical communications and mathematical cipher is being actively studied. To further clarify this advantage, a theoretical concept has been proposed to solve the problem by adopting a PPM code format. However, this scheme has several difficulties at the implementation stage. Thus, this paper presents an optical scheme on modulation and receiver that eliminate those drawbacks.
本文旨在庆祝 D. 佩恩爵士八十寿辰,将我们的最新成果作为他在光通信领域工作的延续。光通信领域的一个重要问题是保护通过光纤通道的传输信息数据。在超高速通信的物理层中,已经提出并正在积极开发实现这一目标的许多想法。例如,通过融合普通光通信中的调制技术和数学密码来实现这一目标的方法正在积极研究之中。为了进一步阐明这一优势,有人提出了一种理论概念,通过采用 PPM 代码格式来解决这一问题。然而,这种方案在实施阶段存在一些困难。因此,本文提出了一种消除这些缺点的调制和接收器光学方案。
期刊介绍:
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
