The publication "Over 70-GHz 4.9-Vppdiff InP linear driver for next-generation coherent optical communications" written by Hersent Romain, Dupuy Jean-Yves, Konczykowska Agnieszka, Jorge Filipe, Blache Fabrice, Riet Muriel, Nodjiadjim Virginie, Mismer Colin, Kasbari Abed-Elhak and Ouslimani Achour is now online. 

This paper presents a 86.8-GHz bandwidth 4.9- Vppdiff (peak-to-peak differential) linear electro-optical (E/O) modulator driver fabricated in III-V Lab’s 0.7-µm InP DHBT technology. On-wafer measurements exhibit a differential gain of 15.1 dB at 0.2 GHz and a 4.1-dB peaking gain at 51 GHz. Record bandwidth and maximum peaking-frequency, for a lumped linear driver, are obtained. Very high quality 100-Gb/s NRZ and 50- GBd PAM-4 output eye diagrams have been measured. A good measurement and EM-simulation agreement is shown. The InP linear driver power consumption is respectively 0.94 and 1.2 W at 4.1 and 4.9-Vppdiff output swings.

In September 2021, Annachiara Pagano and Marco Quagliotti from TIM (Teriphic project partner) participated at ECOC2021, the largest conference on optical communications in Europe, presenting the paper "Disaggregation and Cloudification of Metropolitan Area Networks: impact on Architecture, Cost and Power Consumption".

The article deals with the ongoing change in the architecture of metropolitan area networks, hard-pressed on one side by the deployment of 5G and new wireline systems and on the other side by the emerging of HW/SW disaggregation and cloudification paradigms.
