The laser frequency locking system with high robustness, high accuracy, and good anti-noise performance is usually used in laser synchronization and optics communications, continuous-variable quant…
With the standardizations of 400GE and 400G completed or near completion, the attention is now refocused to next generation techniques with larger bit rates, i.e., 800G. We can see that current res…
Stimulated Brillouin scattering (SBS)-based distributed fiber optic sensing technique has found pervasive applications in measurement of real-world environmental variables. Its sensing capability, …
Network function virtualization (NFV) provides cost-effective network service by means of service function chain (SFC) for users. Meanwhile, billions of terminals are connected to the Internet (Int…
A suite of standards Recommendations has recently been developed in the ITU-T for a 50 Gb/s line rate passive optical network (PON) system. This 50G-PON system represents a significant leap in line…
The Gaussian process regression (GPR), a powerful machine learning tool, is introduced to upgrade the microwave photonic filtering interrogation, with improved demodulation speed and accuracy. In a…
A co-propagating dual-wave interferometer- assisted Brillouin optical time domain analysis (DWI-BOTDA) integrated sensing system is proposed and experimentally demonstrated for high sampling rate d…
An approach of phase-shift transform is proposed and demonstrated to suppress the interference fading in phase sensitive optical time domain reflectometry (Φ-OTDR). The phase-shift transform is ex…
Brillouin optical time-domain analyzer (BOTDA) is used to monitor the temperature and strain along a fiber. So far, neural network and machine learning methods have been successfully applied for te…
