论文摘要
我们与光学发射器一起展示了自由空间的光学通信链接,该发射器从温暖的身体中收获天然存在的普朗克辐射并调节发射强度。发射器利用多层石墨烯设备中的电透明效应,该电气控制设备的表面发射率,从而控制了发射的planck辐射的强度。我们设计了一个振幅调制的光学通信方案,并根据我们的实验性电形表征提供了通信数据速率和范围的链路预算。最后,我们提出了一个实验示范,在实验室尺度上以每秒100位实现无错误通信。
We demonstrate a free-space optical communication link with an optical transmitter that harvests naturally occurring Planck radiation from a warm body and modulates the emitted intensity. The transmitter exploits an electro-thermo-optic effect in a multilayer graphene device that electrically controls the surface emissivity of the device resulting in control of the intensity of the emitted Planck radiation. We design an amplitude-modulated optical communication scheme and provide a link budget for communications data rate and range based on our experimental electro-optic characterization of the transmitter. Finally, we present an experimental demonstration achieving error-free communications at 100 bits per second over laboratory scales.
