自由空间laser通过雾通信

Free space laser telecommunication through fog

Guillaume Schimmel, Thomas Produit, Denis Mongin, Jérôme Kasparian, Jean-Pierre Wolf

摘要:

大气洁净度是自由空间光通信(FSO)的一个关键问题。我们提出了第一个主动的方法来实现FSO通过云和雾,使用超短高强度激光灯丝。激光灯丝以光学机械方式将液滴从光束中排出,并创建一个用于传输1.55微米高比特率电信数据的清除通道。该过程所需的低能量允许考虑使用经典或量子协议应用于地球卫星FSO和安全的地面光通信。

英文摘要:

Atmospheric clearness is a key issue for free space optical communications (FSO). We present the first active method to achieve FSO through clouds and fog, using ultrashort high intensity laser filaments. The laser filaments opto-mechanically expel the droplets out of the beam and create a cleared channel for transmitting high bit rate telecom data at 1.55 microns. The low energy required for the process allows considering applications to Earth-satellite FSO and secure ground based optical communication, with classical or quantum protocols.
