TL;DR: In this paper , the co-propagation over 50km of SSMF of the quantum channel (1310nm) of a QKD system with ~17dBm total power of DWDM data channels (1550nm range) was reported.
Abstract: We report the co-propagation, over 50km of SSMF, of the quantum channel (1310nm) of a QKD system with ~17dBm total power of DWDM data channels (1550nm range). A metric to evaluate Co-propagation Efficiency is proposed.

TL;DR: In this article , the design of a reconfigurable unit cell intended to form a Reconfigurable Intelligent Surface (RIS) is presented at mm-waves frequency, and a solution to control the reflection phase coefficient of this cell and of the resulting RIS is based on varactors diodes allowing to achieve a continuous independent control of the two orthogonal polarizations.

TL;DR: In this paper , a high-speed germanium on silicon APD was demonstrated for DSP-free 50G-PONs, achieving sensitivity of -24 dBm at 58.2 Gbit/s and -26.5 dBm over 60 km of fiber with temperature from -40°C to 80°C.
Abstract: A high-speed germanium on silicon APD is demonstrated for DSP-free 50G-PONs. Sensitivities of -24 dBm at 58.2 Gbit/s and -26.5 dBm at 50 Gbit/s over 60 km of fiber are experimentally obtained in real time with temperature from -40°C to 80°C.

TL;DR: In this paper , the feasibility of multiple transmission channel and multi-rate upstream 50G-PON was assessed for TDEC-based multiple-input-multiple-output (MISO) networks.
Abstract: We assess the feasibility of multiple transmission channel and multi-rate upstream 50G-PON. The TDEC shows that a unique preset filter may be used at both 50Gb/s and 25Gb/s to meet interoperability without adaptive equalization.
