PANTHER an ICT project explained by a video (November 2014)


III-V Lab is involved in the ICT project called PANTHER (www.ict-panther.eu).
PANTHER is a 3-year collaborative project on photonic integration that brings together eight leading European universities, research centers and companies.
The project was launched in January 2014 and is co-funded by the European Commission through the Seventh Framework Programme (FP7).
See the video


III-V lab establishes a new reference for high speed optical communications (October 2014)


As part of FP7/POLYSYS project, III-V lab and the project consortium have demonstrated a 2x100 Gb/s transmitter and a 4x100 Gb/s receiver as key components for multi-100 GbE and 400 GbE optical interfaces in future intra-data center networks.
Compared to other approaches, the two devices can provide significant advantages in terms of number of components, simplicity, footprint and cost, as they are capable of serial operation with non-return-to-zero on-off keying (NRZOOK) format directly at 100 Gb/s.

The transmitter is based on the monolithic integration of a multi-mode interference coupler with two Mach-Zehnder modulators on an electro-optic polymer chip. This chip is co-packaged together with an InP laser diode and two multiplexing and driving circuits. The receiver is based on hybrid integration of a quad array of InP photodiodes with two demultiplexing circuits.
By combining these two devices over standard single-mode fibers without dispersion compensation the consortium achieved a BER better than 10-8 after 1625 m at 2x80 Gb/s, as well as a BER better than 10-7 after 1000 m at 2x100 Gb/s.

Future plans include the development of tunable 100 GbE interfaces for optical circuit switched domains inside data center networks. (FP7/POLYSYS project)

III-V Lab celebrates his 10 years (01 July 2014)

A success model in the III-V components’ high-tech world.

In July 2004, Alcatel and Thales create III-V Lab in gathering and sharing means. Since then, Alcatel becomes Alcatel Lucent, CEA joins the French Group of Economic Interest and the III-V Lab activity domain spreads out…

A particular legal and sales structure
Today, III-V Lab celebrates its 10 years. Over years, this birthday shows the success of the Group of Economic Interest, a French structure between a company and a professional association, which allows several companies sharing their means to extend their economic activity addressing a particular activity domain in common.

Competencies enlarged during years
Initially focused on nanotechnologies and opto-electronic components based on III-V semiconductors (Gallium Arsenide, Indium Phosphor, Gallium Nitride…) the CEA entering allows, with the help of the Leti in Grenoble, to speed up the development of the III-V component heterogeneous integration with Silicon.

A world renowned team
With researchers well known all over the world, invited to present their results in the best international scientific conferences, III-V Lab was able to set up and maintain a network and a collaborative research eco-system that constitutes the engine of our open innovation approach.

Worldwide cooperations in research projects
From now on, III-V Lab is known in the European R&D ecosystem for its collaborative approach and its capability of innovating. Since 10 years, III-V Lab is involved in several European and French research projects and works as well with its mother companies set up all over the world.

Scientific and technical results at the state-of-the-art
At present, III-V Lab teams protect more than 25 patents per year. The ready-to-market technologies of the laboratory are transferred to subsidiaries or to business partners of mother companies, as it happened for infrared detection, transferred to the Sofradir company in 2013.

A sales offer in products and services for Telecoms, Space, Defence and Safety applications
III-V Lab has also received ISO 9001 certificate for its diversified sales offer in III-V components prototypes or pre-series (chips, packaged chips or modules), advanced foundry services (wafers, technology process), or industrial services (thermal, electronic or optoelectronic simulations, made-to-measure circuits modeling, as well as technological transfers).

Using III-V Lab 100G circuit, Alcatel-Lucent demonstrates Tb/s transmission over 3200km (March 2013)


A 1-Tb/s demonstration was shown at OFC/NFOEC conference (19-21 March 2013, Anaheim CA, USA), running during the whole exhibition.
It included a five dual-carrier channels transmission over 3200 km at 5.2-b/s.Hz spectral efficiency, using coherent detection, off-line digital signal processing, and soft-decision forward error correction.

The 1-Tb/s dual-carrier PDM-16QAM (dual-polarization quadrature amplitude modulation) transmission is based on all-electronic 80-GBaud modulation per subcarrier, achieved thanks to the state-of-the-art multiplexer designed, fabricated and packaged in III-V Lab. The performance of this integrated circuit was the key to setting up this demonstration.

This same circuit was used in the experiment reported as postdeadline paper at OFC 2013 conference: "Single-carrier 400G interface and 10-channel WDM transmission over 4800 km using all-ETDM 107-Gbaud PDM-QPSK", by Gregory Raybon and colleagues from Alcatel-Lucent Bell Laboratories, USA, and Agnieszka Konczykowska, Filipe Jorge, and Jean-Yves Dupuy, from III-V Lab, a joint laboratory of Alcatel-Lucent Bell Labs, Thales Research & Technology and CEA-Leti.
