Project description
Overcoming challenges in photonic integrated chip miniaturisation
The EU's aim for faster and more efficient computers has led to exploration beyond current electronics, with great promise seen in photonic integrated chips as a key solution to boost the ongoing digital revolution, while reducing its ICT costs. However, most current photonic technologies employ bulky and single-colour integrated light sources, which limit miniaturisation. Supported by the Marie Skłodowska-Curie Actions (MSCA) programme, the SUPER-QD project aims to overcome this challenge by developing micron-sized on-chip emitters using superlattices of lead halide perovskite quantum dots. This solution would provide more colour channels per device without impeding miniaturisation, offering potential benefits for future transceivers and other components of photonic computers. The project's results are expected to stimulate innovations in photonics and materials science.
Objective
Photonic integrated chips are key for the EU’s pursuit of faster and more efficient computers, aiming to support the Digital Revolution while reducing the costs of ICT. However, progress in photonic devices is held back by challenges in the miniaturization of on-chip light sources. SUPER-QD aims to tackle these challenges by using Superlattices of lead halide perovskite Quantum Dots as micron-size on-chip emitters. Thanks to their color-tunable and bright fluorescence, these nanocrystals solids are efficient micron-size light down-converters, that will allow implementing more color channels per device without compromising miniaturization. Moreover, the coupling between quantum dots results in superior exciton mobility and emission from collective quantum states (superfluorescence), which are promising for future applications in transceivers and quantum computers. SUPER-QD comprises four tasks: 1) Quantum Dots prepared via wet chemistry are assembled into Superlattices with tunable structure. 2) Innovative diffraction techniques are employed to characterize Superlattices, with a focus on structural and energetic disorder. 3) Collective optical properties are studied via space- and time-resolved spectroscopies to discover new structure-coupling relations, with the goal of tuning the Superlattices quantum light emission through their structure. 4) Finally, Superlattices with optimized properties will be installed in Integrated Photonic Chips, to demonstrate on-chip down-converting optical amplification upon photoexcitation from an integrated blue laser. These proof-of-concept devices will create new connections between colloidal nanomaterials and photonic integrated chips, leading to groundbreaking advancements in both fields. SUPER-QD will be hosted by Lund University and the Massachusetts Institute of Technology, leveraging the Fellows’ and Host Institutions’ expertise to ensure a mutual benefit from the Action and the success of the ambitious goals of the project.
