Achieving high budget classes in the downstream link of 50G-PON02/06/2021Abstract:
With 50G passive optical networks (PONs) currently being standardized, we review the challenges of meeting the high loss budgets required in such high speed fiber access networks. Simulations of the 50 Gb/s link performance show the impact of critical parameters when using 25G-class avalanche photodiode receivers with digital signal processing. We describe how a 1342 nm electro-absorption modulated laser, with an external semiconductor optical amplifier, enables an E2-class, 20 km, downstream link for ITU-T, 50G-PON to be demonstrated. Using a 25G-class receiver and real-time equalization, a link budget of 35.6 dB was measured. With more powerful equalization performed offline, an increase in the link budget to 38.2 dB is also demonstrated.

Versatile Externally Modulated Lasers Technology for Multiple Telecommunication Applications07/10/2020Abstract: This paper presents our technological approach for Externally Modulated Lasers (EMLs), based on Semi-Insulating Buried Heterostructure (SIBH) waveguide. We use Gas Source Molecular Beam Epitaxy (GSMBE) to grow the Phosphorus-based multi-quantum wells for both laser and modulator sections with butt-joint integration. The same GSMBE grows the p-doped InP claddings with low-diffusion Be dopant, leading to an accurate control of doping profiles, ensuring very steep modulator extinction curves. We present the main EML design rules and compromises, then apply them to different EMLs aiming at major telecom and datacom applications. After presenting characteristics of the standard 10 Gb/s C-band EML, we propose a 10 Gb/s EML at 1577 nm for next generation access networks, with a record high 10.5 dBm facet modulated power. Then we present high-speed EMLs up to 56 GBaud for datacenter interconnections, both in O- and C-band, aiming at very low peak-to-peak modulation voltage (< 1.2 V), high facet modulated power (> 4.4 dBm), and compatible with uncooled operation (20 to 70 °C). These results confirm the efficiency and versatility of this technological platform for EMLs in a broad range of applications.

Hybrid III–V/Silicon Technology for Laser Integration on a 200-mm Fully CMOS-Compatible Silicon Photonics Platform11/03/2019Abstract:
In this paper, we present the hybrid III-V/Si photonic platform developed in CEA-LETI. The overall integration is done in a fully CMOS compatible 200-mm technology, scalable to 300-mm wafers, leveraging the large-scale integration capabilities of silicon photonics. III-V material is integrated on top of a mature silicon photonic front-end wafer through direct molecular bonding enabling the monolithic integration of light sources. DFB and distributed Bragg reflector (DBR) laser reference designs are used as test vehicles for the process validation. A modular approach is used in order to minimize the impact on the already qualified silicon-based devices. Collective III-V die bonding is proposed in this platform. CMOS compatible metallizations are used to form ohmic contact on n-InP and P-InGaAs leading to contact resistivity in the range of 10 -6 Ω·cm 2 . A planarized two-metal-level BEOL is used to connect the device, leading to a drastic reduction of series resistance. Finally, the functionality of both types of lasers is demonstrated with SMSR up to 50 dB and maximum output power of 5 mW.

III-V Lab and Almae Technologies Press Release29/06/2016“Haute couture” photonics: Almae Technologies takes French excellence and innovation in nanoelectronics, led by III-V Lab, to an industrial scale. Almae Technologies is commercializing an innovative photonic technology developed by teams from Nokia Bell Labs, Thales and the CEA at III-V Lab to address telecom and data storage centers demands for very high speed optical data transmission.
The startup has the industrial infrastructure to rapidly bring to market advanced components required to keep pace with the rapid growth in Internet data volumes. Marcoussis, 29 June 2016 – With the regrouping of teams from III-V Lab (a company under the French “Economic Interest Group” scheme, consisting of researchers from Nokia Bell Labs, Thales and CEA/LETI), Almae technologies is taking over III-V Lab’s facilities at Marcoussis. Spun-off by III-V Lab in October 2015, Almae technologies will use the epitaxy reactors and electronic nanolithography equipment validated by III-V Lab to immediately ready for production III-V semiconductor wafers for the telecommunications market.
With over 2000 m² of clean rooms, Almae technologies will have an annual full production capacity of several thousand semiconductor wafers incorporating new-generation laser components that support very high speed access over optical fiber.
Along with the acquisition of this critical equipment, Almae technologies will benefit from a technology transfer from III-V Lab, with operational support from the laboratory’s R&D teams in laser design, fabrication and characterization. This technology transfer will enable the start-up to rapidly achieve industrial scale and to develop products that meet the growing world market demand for advanced semiconductor lasers based on III- V materials.
“We are delighted to have made this deal with Almae technologies, which brings to the market more than 10 years of research work on access photonics, strengthens our position as a technology leader in the field of laser applications for telecoms and demonstrates the value of our model of an innovative, open industrial laboratory,” comments François LUC, President of III-V Lab.
A growth market serving the needs of tomorrow’s telecoms
The rapid growth worldwide in the number of Internet users, connected objects and data traffic have led to massive use of fiber optics and hence of semiconductor lasers, which are essential for encoding the signal onto an optical carrier for transmission through the fiber.
The market has a strong growth outlook, in particular in Asia and the United States. The optical communications transmitter segment has been assessed at 4 billion dollars and is running at an annual growth rate of 12%.
A technological breakthrough in photonic integration moves out of the laboratory
Almae technologies designs and produces Indium Phosphide (InP) wafers used to implement photonic circuits integrating semiconductor lasers, made possible by licensing a portfolio of patents from Nokia. This involves a technology for growing materials with atomic-scale control developed in III-V Lab: this “buried stripe” laser technology is at the leading edge of global innovation in photonics. It consists of covering the semiconductor strip constituting the laser with an electrical insulator material with sub-micron precision, enabling good thermal exchange and optimum optical guidance of the beam. This technique enhances the implementation, stability and performance of integrated lasers: a range of products operating at up to 25 Gbit/s is in the process of development.
“We are very proud that the photonic technologies developed by Nokia Bell Labs and III-V Lab will now be applied by Almae technologies in the creation of semiconductor wafers for telecommunications industry. Many of these optical technologies are at the core of next generation networks, including 5G. They will provide the greater speed and processing required to meet the needs of a fully mobile and connected society while consuming less power. Almae technologies will also provide a reliable industrial supply chain for our innovations going forward” says Jean-Luc Beylat, President of Nokia Bell Labs France.
“We welcome the agreement with III-V Lab: it will enable Almae technologies to develop its epitaxial wafer manufacturing business on an industrial scale, along with high added value services in collaboration with InPACT, a III-V Lab partner for 10 years, while positioning Almae as a major player in the field of photonic integrated circuits. This new R&D and industrial production activity will contribute to the dynamism of the ecosystem of the Saclay plateau technology region by creating value and highly-skilled jobs in the growing sector of photonics applied to telecommunications,” says Jean-Louis GENTNER, founder and CEO of Almae technologies.
About Almae Technologies
Almae technologies was created in late 2015 at the initiative of one of the directors of III-V Lab and two managers of InPACT, and in February 2016 received a capital input from one of the major players in the photonic components industry. Almae has acquired a set of production equipment belonging to III-V Lab and benefits from a technology transfer from the shareholders of III-V Lab to enable it to become operational very quickly. Almae’s ambitious business plan and the new highly-skilled jobs which it will create will add greatly to the dynamic of the Saclay plateau in the field of photonics.
About III-V Lab
