Ben-Gurion University
Synopsis:
Nanophotonic devices integrated on optical chips represent a groundbreaking class of tools proficient in manipulating light at a minuscule scale, surpassing traditional elements of integrated photonics in performance [1,2]. These devices, characterized by their exceptional speed and energy efficiency, cater to diverse domains such as high-performance computing, chemical and biological sensing [1], energy-conserving illumination [2], and environmental monitoring. Their growing appeal stems from unique traits like expansive evanescent fields, compact design, and crucially, adaptability to specific applications [3]. In my talk I will present recent strides in integrated nanophotonic devices and their versatile applications, spanning mid-infrared and overtone spectroscopy, on-chip all-optical processing [3], logic gates, and cryptographic functionalities [4]. These innovations herald a new era in on-chip nanophotonics, advancing optical waveguides into myriad optical systems and thus are aimed at accelerating the transition of chip-scale nanophotonics from academia to industry[5].

Biography:
Professor Karabchevsky, of Ukrainian origin, is the Director of the Integrated Photonics Laboratory, which focuses on the interaction of light and matter on optical chips and designing innovative interfaces for developments such as single-photon sources and doctor-in-your-pocket devices on a chip. She leads the Integrated Photonics track and teaches Introduction to Signal Processing course (grad), Introduction to Fiber Optics course (post-grad), Integrated Photonics course (post-grad).
Dr Karabchevsky secured more than $7 million USD in funding over the past nine years. More than 14 patents protect her inventions. She has also been involved in disseminating knowledge by editing an Elsevier book entitled “On-Chip Photonics: Principles, Technology and Applications” 2024.
She has held several academic positions, starting as a Teaching Assistant in 2007-2008 at Achva Academic College. Over the years, she progressed through various roles, including Lab Instructor (2009-2011) and External Lecturer at Ben Gurion University of the Negev (2011-2012), as well as an External Lecturer at ORT Braude College (2009-2011). She served (2012-2015) as a Research Fellow at the Optoelectronics Research Center, University of Southampton, UK. In 2015 Dr Karabchevsky joined Ben-Gurion University as a Lecturer. Subsequently, she served as a tenured Assistant Professor (2018-2021), Associate Professor (2021-2023) and later a Full Professor (2023-present) in the School of Electrical and Computer Engineering.
Dr. Karabchevsky founded the SPIE students chapter the first in the Middle East, in November 2010, a member of IEEE (since 2020) and IPS (since 2019). She is Chair of the Women in Engineering Affinity Group, IEEE Section (since 2020). She has various editorial roles, including Editor for Advanced Photonics Research Journal (Wiley) and Guest Editor for Sensors Journal (since 2020). She has received numerous awards, including 2019 and 2017 recognized as one of the Top 100 Official authors in Physical Sciences of Scientific Reports journal, 2014 'Brilliance in Research' award of Optoelectronics Research Centre, University of Southampton, UK, 2012 President’s Award for 'Outstanding Woman in Science,' which included a monetary prize of $45,000, 2011 Best Paper at the SPIE Optics and Photonics Conference in San Diego.
In addition to her editorial roles for top journals such as Advanced Photonics Research and Sensors, Dr Karabchevsky has been instrumental in organizing and chairing significant international conferences, including the International Conference and Exhibition on Optics and Electro-Optics (OASIS) and the 7th Nano Israel Conference (Nano.IL.2020), where she served as the Bio-Nano Medicine Session Chair.
She served on numerous international expert panels, including those of the Research Council of Canada, the European Commission, and other national and international organizations.
