Protecting the security of optical network is a major worldwide challenge. The conventional schemes for securing communications are based on cryptography at the MAC layer and its higher layers, whi…
Optical performance monitoring (OPM) is an important tool to facilitate the management of future optical fiber communication networks. OPM measures the states of the physical layer and provides fee…
In extreme environments such as abysmal sea and deep space, the characteristics of low-temperature, vacuum, electromagnetic interference will significantly affect the performance of measuring instr…
Actively controlling the amplitude and phase of terahertz (THz) wave is of great significance for THz broadband wireless communication and high-resolution THz imaging. In this paper, we present a T…
The performance of free-space optical data transmission is severely deteriorated by the fluctuation of optical signal intensity, which is resulted from the bias drift of electro-optical modulation …
Recently, the integration of two-dimensional materials with optical fibers has opened up a great opportunity to develop all-fiber signal-processing devices. Graphene is an ideal material for all-op…
Efficient synchronization is of great importance for fiber optical coherent communication system. Here, we propose an accurate and low-complexity timing/frequency synchronization scheme based on sp…
