NTUA at SPIE Photonics West 2025 in San Francisco, California (USA)
January 28, 2025From 25 to 30 January 2025, our coordinator National Technical University of Athens participated in the SPIE Photonics West 2024, the world’s premier event for lasers, biomedical optics and biophotonic technologies, quantum, and optoelectronics, which took place in San Francisco, California (USA).
The conference included multiple symposia and technical sessions covering areas such as biomedical optics, photonics, lasers, optoelectronics, micro/nanofabrication, and more. It provided a platform for researchers, engineers, scientists, and industry professionals to share and discuss the latest advancements in photonics research, technology, and applications. It also featured an exhibition showcasing the latest products and innovations in the field.
Our partner had the chance to present, on 28 January, Next-2Digits’ latest results on the “Laser-induced transfer and processing of graphene into plasmonic structures of advanced photodetectors”, work carried out by Prof. Leonidas Tsetseris, Dr. Filimon Zacharatos, Kostas Andritsos, and Prof. Ioanna Zergioti. Below you can find the abstract of the presentation:
One way to enhance the efficiency of graphene-based optoelectronic devices, e.g. photodetectors, is to incorporate suitable plasmonic structures, a task which is challenging in terms of, e.g., cost and scalability. Here, we report results on an alternative method, namely the so-called Laser Induced Forward Transfer (LIFT), to produce arrays of graphene pixels with interspersed micro-scale metallic structures. The LIFT technique has proven to be highly versatile and effective in the digital fabrication of high-quality, high-resolution graphene pixels of various sizes. The results of the present study show how these advantageous features of LIFT can be utilized to enhance the performance of graphene-based photodetectors.
