Abstract

We present a compact, agnostic transmitter capable of simultaneously transmitting all types of signals (analog and digital with different modulation formats) with a single-ring modulator with a radius of 10 micrometers and a bandwidth of around 18 GHz. To the best of our knowledge, we show for the first time, experimental results for transmitting three different Nyquist BPSK signals with an aggregated baud rate of 24 GBd in such a compact device. Additionally, we show the simultaneous transmission of a 3 GHz analog signal together with normal and Nyquist-shaped 4 GHz BPSK signals. All results were achieved without any power-consuming pre- or postprocessing to adapt the signals to the transfer function of the modulators. The simultaneous transmission of analog and digital signals in a device with a small footprint and low power consumption may be especially advantageous for future access networks.

利用单环调制器同时传输模拟信号和不同数字信号的紧凑型高能效技术

我们展示了一种结构紧凑、不受环境影响的发射器，它能够利用半径为 10 微米、带宽约为 18 千兆赫的单环调制器同时发射所有类型的信号（采用不同调制格式的模拟和数字信号）。据我们所知，我们首次展示了在如此紧凑的设备中传输三种不同的 Nyquist BPSK 信号的实验结果，其总波特率为 24 GBd。此外，我们还展示了同时传输 3 GHz 模拟信号以及普通和奈奎斯特形 4 GHz BPSK 信号的情况。所有结果都是在不进行任何耗电的预处理或后处理的情况下实现的，以便使信号适应调制器的传递函数。在一个占地面积小、功耗低的设备中同时传输模拟和数字信号，这对未来的接入网络可能特别有利。
