We use ANN models to estimate the performance of latency-critical and delay-tolerant tasks when applying edge cooperation in EC-enabled EONs. Using the performance estimation, a resource allocation scheme is proposed to jointly optimize multiple performance.

We experimentally observed the buildup process of conventional and bound optical solitons via time stretched dispersion Fourier transform technique in two Erbium doped fiber lasers. The mode locking with femtosecond soliton operation was realized by the nonlinear polarization rotation mechanism. The result shows that the random pulses generated firstly, then small pulses was reduced and the main pulse was narrowed and strengthened to form the optical soliton, steady soliton operation was realized after a rapid self-frequency-shifting. The bound soliton was formed as single soliton separation with time interval variation.

In order to ensure the data validity of the GNSS dam deformation monitor with high precision, a method for calibrating the GNSS satellite dam deformation monitor with high precision is presented, which makes the GNSS satellite dam deformation monitor with high precision trace to the national standard effectively. First, the working principle of the GNSS satellite dam deformation monitor with high precision is analyzed. Next, using the GNSS receiver calibration field, calibrate the indication error of the high-precision GNSS dam deformation monitor. Finally, the calibration data is summarized and analyzed, and the uncertainty of the calibration results is evaluated. The experimental results show that the plane measurement accuracy of the GNSS dam deformation monitor with high accuracy is 2mm. The height measurement accuracy is 1 mm and the uncertainty is 0. 6mm, to meet the traceability requirements of high-precision GNSS satellite dam deformation monitor.

The NA is a basic parameter of a lens, which can determine its focusing spot size in the far field. High NA(close to 0.9 or above) metalens with a deep sub-wavelength focusing spot is an important metadevice in the modern optics and photonics. In this paper, a four-layer microwave metalens and its applications in the high-gain and low-profile antenna are studied and demonstrated. A high NA=0.88 (FWHM is 0.57λ) metalens based on high transmission phase gradient metasurface is firstly designed and is also verified by experimental result. Besides, a feeding source is placed at the focal spot of the proposed metalens, and a quasi-spherical wave is emitted and then transformed to a plane wave. Thus, a high gain antenna is obtained and the beam-width of the bare antenna is also significantly decreased. The simulated results show that the gain of the high NA metalens is largely enhanced by 10.47dB compared to bare antenna at the frequency of optimized 9GHz. More importantly, the relation between the focusing efficiency of high NA metalens and the enhanced gain of lens antenna is discussed and highlighted. The work opens new avenues to design high-gain lens antenna based on high NA plasmonic metalens in the microwave band.

A comprehensive nonlinear filter scheme for 50Gb/s PAM4-PON systems is proposed in this paper. In our scheme, both the forward symbols and the backward symbols of the Volterra filter are considered and the decision term is added after the Volterra filter to better eliminate the inter-symbol interference (ISI). An experiment of 50Gb/s PAM4 transmission is demonstrated over 20 km SSMF. Results show that a link power gain of 1.3 dB can be obtained at the HD-FEC threshold (3.8×10−3) compared to the Volterra filter.

Cable tunnel is easily affected by external force, such as excavating equipment, which leads to abnormal cable and affects normal transmission. In order to detect the abnormal phenomenon of cable tunnel in time, the optical fiber sensing technology is used to monitor the cable tunnel in real time. Four fiber vibration sensors are installed on the roof of cable tunnel and connected to the self-developed optical fiber microseismic monitor. Different vibration signals are simulated directly above the cable tunnel, the time domain and frequency domain information generated by the vibration signal are analyzed, and the source type of the disturbed cable tunnel is identified in order to protect the cable tunnel in time. The results show that there are obvious differences in the main frequency produced by different source types, and the source information can be classified according to different main frequency signals, especially the information of external force damage, so as to protect cables in time and ensure the safety of electricity consumption.

In this paper a series of solution processed green phosphorescent organic light-emitting diodes (PhOLEDs) based on blend hosts-guest configuration have been fabricated and the effect of various hole transport materials, e.g. 1,3-Di-9- carbazolylbenzene (mCP), poly(9-vinylcarbazole) (PVK) and 4,4′,4″-tris(N-carbazolyl)-triphenylamine (TCTA) and their combination as the hosts on the performance of PhOLEDs have investigated. It is found that the device with the ternary blend host (mCP:PVK:TCTA) doped with tris(2-(p-tolyl)pyridine-C2,N)iridium(III) (Ir(mppy)3) as a green guest material can achieve a luminance of 10213 cd m-2 at a driven voltage of 7 volts, the uppermost external quantum efficiency (EQE) of 16.91%, and a small roll over and maintain EQE of 12.95% at 1000 cd m-2 with the CIE coordinates of (0.31,0.61). Compared with the corresponding single and binary host systems (mCP, 4600.49 cd m-2, 14.62%, 24.90%; PVK, 5116.74 cd m-2, 15.77%, 19.78%; mCP:PVK, 5275.05 cd m-2, 16.99%, 22.07%), the PhOLED based on ternary-host materials has the optimal performance. The superior electroluminescence (EL) performance for ternary blend host-based green PhOLEDs was attributed to the efficient energy transfer from the host to dopant, the appropriate highest occupied molecular orbital (HOMO) level and the enhanced charge carrier transport balance.
