The Photonics Communication Research Laboratory had a strong presence at SPIE Photonics West 2025.
Adamantia Maria Grammatikaki presented the poster titled “Development of 3D-printed micro-lenses at the edge of waveguides of flow cytometry and optical coherence tomography photonic integrated circuits.” This research highlights a novel biophotonic platform that integrates Flow Cytometry (FCM) and Optical Coherence Tomography (OCT) for the detection of extracellular vesicles (EVs) as small as 140 nanometers.
Key to this breakthrough is the development of 3D-printed micro-lenses that enhance coupling efficiency between photonic and fluidic systems, achieving optical losses as low as 0.3 dB. This innovation, aimed at improving healthcare diagnostics, demonstrates the potential of photonics to support early diagnosis and treatment of diseases such as cancer and stroke.
Also, Charalampos Zervos presented AEOLUS Project paper “Leveraging a SiPh Mid-IR Platform for Integrated Thermal Source and Detector to Measure CO₂ and CH₄ Levels.” This research focuses on a silicon photonics platform designed to detect critical greenhouse gases, offering a compact, high-precision solution for environmental monitoring.
The study integrates both thermal sources and mid-infrared detectors on a single photonic chip, paving the way for innovative tools that can enhance sustainability efforts by monitoring carbon dioxide (CO₂) and methane (CH₄) concentrations with improved accuracy and efficiency.
The paper is a collaborative effort by:
Charalampos Zervos, Georgios Syriopoulos, Evrydiki Kyriazi, Thenia Prousalidi, Pen-Sheng Lin, Kristinn B. Gylfason, Frank Niklaus, Shayan Parhizkar, Stephan Schroeder, Floria Ottonello Briano, Stephan Suckow, Max C. Lemme, Giannis Poulopoulos, Dimitrios Apostolopoulos and Hercules Avramopoulos.
These presentations underscore PCRL’s dedication to advancing photonic technologies across a wide range of applications. From biophotonic platforms that support early disease diagnosis to silicon photonics-based solutions for environmental monitoring, PCRL continues to excel in photonics research, driving innovation to address global challenges.
