Near Infrared Perovskite Light Emitting Diodes Integrated into a Silicon Nitride Photonic Platform: Technologies Hybridization

Objective

IPER-TECH will demonstrate the integration of an array of efficient tin-based perovskites LEDs, with steerable emission in the NIR-I spectral range, into a photonic integrated platform based on silicon nitride. The latter is recognized as a key technology due to its compatibility with the complementary metal–oxide–semiconductor (CMOS) manufacturing infrastructure and the potential for integration with back-end-of-line Si microelectronics. Integrated optical platforms are an essential development for the implementation of complex functionalities that are becoming increasingly sophisticated in their applications.IPER-TECH will demonstrate the integration of an array of efficient tin-based perovskites LEDs, with steerable emission in the NIR-I spectral range, into a photonic integrated platform based on silicon nitride, which is recognized as a key technology due to its compatibility with the complementary metal–oxide–semiconductor (CMOS) manufacturing infrastructure and the potential for integration with back-end-of-line Si microelectronics. Integrated optical platforms are an essential development for the implementation of complex functionalities that are becoming increasingly sophisticated in their applications. In this context, a big technological gap is present in the NIR spectral range, which cover nearly all aspects of our daily life. In fact, commercial NIR light emitting diodes (LEDs), which commonly employ epitaxial heterostructures of III–V inorganic semiconductors as emitting materials (e.g., GaAs, InGaAs, etc.), cannot be integrated. The demonstration of a new hybrid technology for photonic applications will enable otherwise unachievable functionalities for diversified applications ranging from night vision to optical communications, data storage and biomedical treatments and lay the foundation of the first technology of light-emitting sources in the Near-Infrared (NIR) spectral range whose architecture can be customized and integrated in complex systems.
