Abstract

Abstract : Photodetection and light emission in the short‐wave infrared is of paramount importance for a large spectrum of applications including night vision, surveillance, automotive imaging in adverse conditions, spectroscopy for food quality and process monitoring just to name a few. To address this large consumer market volume the necessity for low‐cost CMOS‐compatible infrared photodetectors and light emitters is therefore indispensable. We present recent research efforts at ICFO on the development of highly sensitive CMOS compatible photodetectors based on hybrid 2D and QD materials delivering performance on par with costly epitaxial counterparts and present some applications employing those detectors in imaging and health monitoring. We further discuss progress on the development of highly efficient SWIR light emitters tunable from 1.3–1.7 um with quantum efficiency of 8% and improved droop and stability.
