近年来, 以激光大气传输为应用背景的光束相干合成技术被广泛研究, 而关于该项技术在空间光
通信中的应用研究却不多. 事实上, 基于光束相干合成的多孔径接收天线结构可有效缓解大气 …

In free-space optical communication links, the combining of optical signals from multiple
apertures is a well-known method to collect more power for improved sensitivity or mitigation …

Free-space optical (FSO) communications has potential advantages of higher data capacity
and lower probability of interception, when compared to radio-frequency communications …

Performance of optical wireless communication (OWC) in outdoor environments can be
significantly degraded due to the fog and pointing errors. In this letter, we consider a multi …

Differential phase shift keying (DPSK) modulation and multi-aperture receiving are effective
means for suppressing flickering, deviation, and fragmentation of the light spot by …

Free-space optical satellite-earth links often operate at the SNR limit. We show that under
low SNR conditions it is more favorable to operate at higher speeds with lower order …

We propose and experimentally demonstrate the mitigation of adverse effects of scintillation
using a spectrum-sliced incoherent light source based on gain-saturated reflective …

Performance of the direct-detection coherent receiver array for free-space optical (FSO)
communications is evaluated with a full-link simulation model. This FSO full-link model (from …

In coherent optical communication, the application of linearly polarized light can greatly
improve communication sensitivity and communication capacity. However, when a laser …

Mode diversity reception is experimentally investigated using an optical turbulence
generator, off-axis digital holography, and digital demultiplexing. The results confirm …
