Fiber-optic sensors have developed rapidly because of their excellent sensing
performances and abilities to detect in remote and harsh environments. However, on some …

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 …

Optical signal-to-noise ratio (OSNR) monitor is a key unit in the modern optical networks,
serving as an indicator of the transmission link quality. With the demand for cost efficiency …

Due to the exponentially increasing connectivity and bandwidth demand from the Internet,
the most advanced examples of medium-scale fast reconfigurable photonic integrated …

We propose a novel in-band optical signal-to-noise ratio (OSNR) monitor based on
asymmetrical parallel Mach-Zehnder interferometers (A-PMZI). By exploiting two different …

We propose a novel in-band optical signal to noise ratio (OSNR) monitoring technique in
digital coherent receiver based on fractional Fourier transform (FrFT), which employs the …

Line waves are defined as confined edge modes propagating at the interface of dual
electromagnetic metasurfaces that preserve mirror reflection symmetries. Previous works …

We propose and experimentally demonstrate a novel in-band optical signal-tonoise ratio
(OSNR) measurement method based on normalized autocorrelation function. Experimental …

In this paper, and for the first time in literature, optical performance monitoring (OPM) of
super-channel optical networks is considered. In particular, we propose a novel machine …

Based on different coherence properties of signal and noise, we measured the in-band
optical signal-to-noise ratio using an integrated thermally tunable Mach-Zehnder optical …
