The Politecnico di Milano (POLIMI) contributed to the Single Photon Workshop 2024 (SPW2024), held in Edinburgh on November 18-22, 2024, by presenting their cutting-edge research on photon detection efficiency.
At this premier international event, dedicated to single-photon technologies, POLIMI, represented by Simona Sorrentino, showcased a poster titled “From front-side to back-side illumination of InGaAs/InP SPADs for photon detection efficiency enhancement”.
The poster detailed the innovative conversion of InGaAs/InP Single Photon Avalanche Detectors (SPADs) from frontside illumination (FSI) to backside illumination (BSI). This conversion resulted in an impressive 50% enhancement in photon detection efficiency. This advancement not only represents a significant step forward in photon detection capabilities but also paves the way for the seamless integration of these SPADs with photonic integrated circuits in QPIC1550.
The insights presented at SPW2024 underscore the importance of innovation in quantum technologies and POLIMI’s pivotal role in advancing the QPIC1550 mission. By improving photon detection efficiency, POLIMI continues to contribute to the project’s vision of creating scalable and high-performance quantum photonic solutions operating in the telecom C-band.
