The trade-off between more user bandwidth and quality of service requirements introduces
unprecedented challenges to the next generation smart optical networks. In this regard, the …

This study addresses the issues of optical network survivability to attacks in the optical
physical layer. The authors comprehensively review and discuss the vulnerability of optical …

We developed an optical processing platform that handles over 100 space-division-
multiplexed signals in the C-band. The device consists of free-space optics based on liquid …

We report on a compact (footprint) silicon photonics integrated system performing high-
sensitivity monitoring of in-band optical signal-to-noise ratio (OSNR). The system, including …

We propose a novel and in-service method for in-band OSNR system margin and overall
link impairment level monitoring based on the use of an optical coherent receiver. This …

We experimentally studied the performance of a delay-line interferometer-based optical
signal-to-noise ratio (OSNR) monitor that is pre-calibrated in optimal conditions for 25 …

At present, the power communication network has many evaluation indexes, but the existing
OTN operation risk evaluation index is only a simple statistical index, and lack of analysis …

A narrowband optical filter on Silicon-on-Insulator based on a directional coupler of
continuous and periodic segmented waveguide is theoretically investigated. The study …

A high sensitivity in-band OSNR monitor system integrated on SOI platform is presented.
The device exploits a narrow-band microring resonator to select the portion of the channel …

In this work, a novel estimation method is proposed for in-band noise monitoring in short
distance optical communication systems based on the sub-space method. In the polarization …
