Swiss IEEE EPS Webinar- High-speed datacom 400Gb/s transceiver with reduced manufacturing cost


Higher speed and high-volume production at low cost are the two main factors that will drive the development of next generation optical modules for datacom applications.

This webinar will focus on application of 400Gb/s transceivers in datacom and the challenges of low-cost packaging. Dr. Hélène Debrégeas from Almae Technologies with talk about the development of transmitters using 4 InP-based laser-modulators operating at 100Gb/s and Dr. Christophe Petit from Albis Optoelectronics will talk about the development of receivers based on 4x56 Gbaud photodiode arrays with backside lenses.

Dr. Hélène Debrégeas of Almae Technologies


Hélène Debrégeas received Engineering degree from Telecom ParisTech in 1994, Mathematics Agrégation teaching certificate in 1995, and Ph.D on widely tunable lasers in 2007. She has worked for more than 20 years at Alcatel Research center (now Nokia Bell Labs, within III-V Lab) on InP transmitters such as electro-absorption modulated lasers, widely tunable laser, and Silicon photonic integrated circuits. From 2012 to 2014, she worked at Nokia Bell Labs Murray Hill (NJ, USA) on hybrid integration of InP transmitters and silica passive waveguides. In 2018 she joined Almae Technologies, a spin-off from III-V Lab, focused on developing and producing InP transmitters for telecommunication applications. She is in charge of research and innovation, to develop next generation products and their hybridization with other technologies or packaging. She contributed to more than 50 peer-reviewed journal and conference papers, 20 patents, and a Springer book chapter on widely tunable lasers.

Dr. Christophe Petit of Albis Optoelectronics


Dr. Christophe Petit obtained his MSc. in Material Sciences from the National Institute of Applied Science in Rennes (INSA), France, and a PhD from Denis-Diderot University in Paris, France, after his work on the electro-optical thermal transition of thin film oxides at the Laboratory of Optical Solids. He has worked at CILAS, France, on infrared gas lasers and at the Fraunhofer Institute for Applied Optics, Germany, on light scattering of Deep UV optics. He joined Opto Speed in 2001 as R&D engineer and when Albis Optoelectronics has been launched In 2003 he was already part of the photodiode development team. He is nowadays managing the p-i-n photodiode product line, specializing in ultra-high speed InGaAs and GaAs photodiodes and is working on the development of next generation products.
