Sergio Nicoletti
Optical Sensor Devices Group, CEA – Leti


Si-Based photonics platform at CEA Leti


Recently, we have seen a tremendous progress in the development of photonic-based sensors for many applications. Silicon photonics can provide inexpensive photonic chips due to excellent electronic and photonic properties for sensing, computing and communication. CEA - Leti versatile photonic platform offers a broad range of processes with up-to-date industrial equipment. More than silicon is provided, with the integration of amorphous Si, SiGe, Ge, SiN layers and III-V bonded epi layer on the same wafer covering from visible to Mid-IR. This talk will review the fabrication capabilities offered by our platform, which allows large-scale integration of active and passive devices in a flexible CMOS compatible process.


Working on gas sensing and microsystem technologies since the early 1990s, Sergio Nicoletti joined CEA-Leti in 2006 to develop Mid-IR optical gas sensors. Since then he has served as chief researcher and project leader in several collaborative and industrial projects. Now Sergio is in charge of the development of industrial partnerships in this field. Sergio earned a Ph.D. degree in physics from Université Joseph Fourier, Grenoble.
