TERIPHIC paper entitled “Uncooled 100 GBd O-Band EML for Datacom Transmitter Arrays” is now on our website!
The paper presented at OFC 2022 by Fraunhofer-HHI.
The paper successfully demonstrates the 100 GBd performance of an array-compatible O-Band InP EML in a temperature range from 30°C to 70°C. The EML chip utilizes a common active layer design, and a booster SOA increases the optical output power and equalizes it to 10 mW for all operation temperatures and it is written by Ute Troppenz, Michael Theurer, Martin Moehrle, Ariane Sigmund, Marko Gruner, and Martin Schell.

The publication "Enabling low-cost high-volume production compatible terabit transceivers with up to 1.6 Tbps capacity and 100Gbps per lane PAM-4 modulation for intra-data center optical interconnects up to 2km: The TERIPHIC project approach" written by P. Groumas, C. Tsokos, D. Felipe, U. Troppenz, R. Hersent, P. Bakopoulos, B. Atias, J. Y. Dupuy, A. Pagano, A. Chiado Piat, S. Kibben, L. Gounaridis, A. Raptakis, M. Seyfried, M. Moehrle, C. Kouloumentas, N. Keil and H. Avramopoulos is now online.
According to the publication, existing transceiver technology inside data centers will soon reach its limits due to the enormous traffic growth rates driven by new, bandwidth-hungry applications. Efforts to develop the next generation of 800Gbps and 1.6Tbps transceivers for intra-DC optical interconnects have already kicked-off to address the demands in traffic, the exhaustion of the ports at the digital switches and the power consumption limitations inherent to the use of many lower capacity modules. The new generation of optical modules must also provide Terabit capacities at low cost, necessitating the use of high-volume manufacturing processes. TERIPHIC is an EU funded R and D project that aims at developing transceiver modules with up to 1.6 Tbps capacity over 16 lanes in duplex fiber and cost less than 1 € per Gbps for distances up to 2 km, utilizing PAM-4 modulation for 100Gbps per lane and high-volume production compatible transceiver designs. At the component level, TERIPHIC will rely on arrays of high-speed electronics, InP Externally Modulated Lasers (EMLs) and InP photodetectors, and at the integration level it will rely on a polymer photonic platform as a host motherboard, leveraging its flexibility and powerful toolbox. A summary of the progress on the TERIPHIC transceiver modules concept, both at the component level and integration level is presented in this paper.

The publication "Disaggregation and Cloudification of Metropolitan Area Networks: impact on Architecture, Cost and Power Consumption" written by Marco Quagliotti, Laura Serra and Annachiara Pagano is now online.
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.

TERIPHIC project will participate at OFC 2022 with a paper presentation by our project partner Fraunhofer HHI.
The paper that will be presented is entitled "Uncooled 100 GBd O-Band EML for Datacom Transmitter Arrays" and it is written by Ute Troppenz, Michael Theurer, Martin Moehrle, Ariane Sigmund, Marko Gruner and Martin Schell.
According to the paper, 100 GBd is demonstrated from 30°C to 70°C with O-Band InP EML array chips. Modulation bandwidths are above 50 GHz, and an integrated SOA ensures 10 dBm, while a single active layer allows for cost-effective manufacturing.
The presentation will be given by Ute Troppenz, during the session “High-speed Semiconductor Lasers”.

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.
