Optics and photonics
In photonics, information is carried by photons. Light is emitted by a laser at a given wavelength; a modulator then generates a pulse, which travels through a series of passive components before being transmitted by optical fiber to a receiver for conversion into an electronic signal. The EU PLAT4M project is focusing on this type of optical transmitter-receiver system.
Leti, a member of the PLAT4M project consortium, helped to develop a new silicon photonics platform suitable for short-range (between servers within a data center) optical communications. The technology is mature enough for industrial scale-up. The 200 mm pilot manufacturing line developed can be used to make passive components, detectors, modulators, and integrated lasers.
In addition, Leti developed an open-access multi-project wafer service to provide businesses with easier access to photonic component manufacturing resources and transferred the service to the CMP service center for rollout.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
