Nanomaterials for Infrared Silicon Photonics
NOMISS aims to develop cost-effective, small-footprint printable IR opto-electronics using non-restricted colloidal quantum dots for enhanced light emission and integration with photonic circuits.
Projectdetails
Introduction
Printed opto-electronics based on solution processable colloidal semiconductor quantum dots (QDs) can make available a much-needed small footprint, low cost and flexible platform for optical sensing, imaging and spectroscopy in the technologically relevant short and mid-wave infrared (IR) spectrum (1.5 µm - 5 µm).
Current Challenges
However, while this revolution took place in the visible spectrum, and is happening at the side of detection for IR light, QD IR light source technology is currently:
- Expensive
- Lacking performance
- Based on restricted chemical elements
Moreover, final device assemblies have large footprints, limiting their functionality in consumer devices requiring large scale deployment.
Project Goals
In NOMISS, I will therefore explore a route towards printable IR opto-electronics by developing a new class of solution-processable QDs based on non-restricted elements with efficient IR emission.
Research Focus
I will study both their fundamental IR light-matter interactions, aimed at increasing light emission efficiency, and the possibility to incorporate them with small-footprint photonic integrated circuits (PICs).
Methodology
To this end, I will:
-
Extend the bottom-up chemical synthesis of tunable III-V In(As,Sb,P) QDs.
-
Study their (non-)linear optical properties using a novel ultrafast and broadband IR optical spectroscopy methodology, particularly focusing on:
- Fundamental questions related to the QDs organic/inorganic interface
- Optimization of spontaneous & stimulated IR emission
-
Develop a framework to combine these materials with silicon-based PICs to realize cheap & small-footprint IR light sources, particularly optically pumped lasers.
Future Impact
After NOMISS, the new cross-disciplinary and high-impact field of 'printable IR opto-electronics' will be available.
Team Leadership
To meet these high-risk challenges, I will lead a multi-disciplinary team with experts in nanochemistry, nanophysics, and nanophotonics engineering.
