Solid indium phosphide (INP) tunable lasers for telecommunications networks are costly to manufacture and ill-suited to integration with other photonic and electronic components. Researchers from Leti and the III–V Lab have now produced a tunable laser on a silicon substrate coupled with a III–V material. This hybrid monomode laser boasts a novel waveguide system coupled […] >>

Just one year ago, researchers at Leti built an 80 Gb/s data switch demonstrator; today, they have set a new speed record with a switch prototype that works at 128 Gb/s or 256 Gb/s. And, once again, the results are the fruit of a multi-partner project involving Alcatel-Lucent and the III–V Lab. The system will […] >>

Researchers from INAC and Liten have developed a new-generation solid electrolyte based on thermotropic ionic liquid crystals. The purpose of the research was to improve lithium-ion battery safety and performance. The crystals self-organize into nanometric strips and help prevent the charge buildup and thermal runaway that can cause liquid-electrolyte batteries to catch on fire or […] >>

Researchers at Leti have developed a reader and ASIC for RFID data reception at speeds up to 27.12 Mb/s required by the ISO 14443-amd5 standard. The new technology could be used for electronic passports, which will store more and more information, from biometric data to secure protocols. Tomorrow’s fourth-generation electronic passports could even be used […] >>

Researchers at Leti have reduced the thickness of antennas for satellite communications and tomorrow’s 5G network access points by half. Their secret? They replaced the single focal point of today’s antennas with a four-source focal network. A 30 GHz antenna leveraging the innovation measures just 10 cm x 10 cm and is just 3 cm […] >>
