In this article, we present a 300-GHz wireless link composed of a photonic uni-traveling-carrier diode transmitter and an active electronic receiver based on millimeter wave integrated circuits fabricated in an InGaAs metamorphic high electron mobility transistor technology. The input pseudorandom binary sequence is transmitted and analyzed offline using fast analog-to-digital converters. The data transmission reaches,100 Gb/s over a distance of 15 m. Complex modulation formats, such as 32-quadrature amplitude modulation and 64-quadrature amplitude modulation, are successfully transmitted up to a symbol rate of 8 GBd. The system presents not only high linearity but is also capable of transmitting high symbol rates, up to 40 GBd. To the best of the authors’ knowledge, this represents the highest ever reported transmission bandwidth as well as the highest spectral density symbol rate product for transmissions with center frequency in the terahertz band. Thus, the usage of such links in future bandwidth-hungry applications, such as data centers, data showers, fronthaul, and backhaul, is proven feasible.

采用传输带宽为 54 GHz 的光子发射器和有源电子接收器的 300 GHz 无线链路

在本文中，我们展示了一个 300 GHz 无线链路，它由一个光子单行载流子二极管发射器和一个基于毫米波集成电路的有源电子接收器组成，该电路基于采用 InGaAs 变质高电子迁移率晶体管技术制造的毫米波集成电路。使用快速模数转换器离线传输和分析输入的伪随机二进制序列。在 15 m 的距离内，数据传输达到 100 Gb/s。复杂的调制格式，例如 32 正交幅度调制和 64 正交幅度调制，可以成功传输高达 8 GBd 的符号率。该系统不仅具有高线性度，而且能够传输高达 40 GBd 的高符号率。据作者所知，这代表了有史以来报告的最高传输带宽以及中心频率在太赫兹频段的传输的最高频谱密度符号率乘积。因此，在未来需要大量带宽的应用程序（例如数据中心、数据淋浴、前传和回传）中使用此类链路已被证明是可行的。
