摘要

光纤无线电(RoF)网络利用光介质的高带宽和低损耗在光载波上传输射频信号。最高水平的收敛可以通过光纤到天线(FTTA)设置来实现。我们展示了一个高度集成的光纤耦合接收天线,可以直接连接到标准光网络。在不需要外部仪器的情况下,天线本身拥有将接收信号转换为光域的所有必要电路,即激光二极管及其驱动器和前置放大器。使用维瓦尔第天线,可以达到133%的高相对带宽。给出了天线的设计和优化,并对天线系统的结果进行了讨论。

Active integrated fiber-coupled receiving antenna
Radio-over-Fiber (RoF) networks take advantage of the high bandwidth and low losses of optical media to transport RF signals on an optical carrier. The highest level of convergence can be achieved by Fiber-to-the-Antenna (FTTA) setups. We demonstrate a highly integrated fiber-coupled receiving antenna that can be directly connected to a standard optical network. Without the need of external instrumentation, the antenna itself holds all necessary circuitry to convert the received signal to optical domain, i.e. a laser diode as well as its driver and preamplifiers. Using a Vivaldi antenna, a high relative bandwidth of 133% can be reached. The design and optimization of the antenna together with the electronics is shown and antenna system results are given and discussed.
