Photonic Detection

This group involves the detection of photons as received from images, data links, and experimental spectroscopic studies to mention a few. Within its scope, it is involved in the design, fabrication, testing of single and arrayed detectors. Detector materials, structures, and readout circuitry needed to translate photons into electrical signals are considered by this group. Also included in this group is the integration of components such as lens, cold shields, and readout electronics into cameras. Research into higher efficiency, lower noise, and/or wavelength tunability is included here. Additionally, techniques to mitigate noise and clutter sources that degrade detector performance are within the purview of this group. In the imaging area, camera design, componentry, and circuitry are considered.

Fiber Optic Sensing and Biosensing

Join the OSA Photonic Detection Technical Group for this webinar featuring Francesco Chiavaioli from the National Research Council (CNR) Institute of Applied Physics "Nello Carrara" (IFAC). Given the growing interest in fiber optics-based devices, the aim of this webinar is to provide the fundamentals and a metrological assessment of resonance-based fiber sensing and biosensing platforms, as well as to detail some state-of-the-art remarkable examples in real applications.

In the first part, the attention will be focused on some fundamentals of fiber sensors and the most common parameters used to describe the performance of any fiber sensing and biosensing platform by underlining the difference between volume or bulk sensing and surface or add-layer sensing (or biosensing). In the second part, some remarkable examples of resonance-based fiber optics devices from the state-of-the-art literature will be presented. In particular, the combination of such devices with nanotechnology, such as deposition of nanocoatings, nanoparticles or nanostructures in general, will be deeply discussed with final “food for thoughts” examples.

Subject Matter Level:

  • Intermediate - Assumes basic knowledge of the topic

What You Will Learn:

  • Fundamentals of sensing and biosensing with fiber optics
  • Metrological assessment of resonance-based optical sensing platforms
  • State-of-the-art literature regarding fiber optics sensing and biosensing with some "food for thoughts"

Who Should Attend:

  • Ph.D. students, post-docs and researchers working in related or similar fields

About the Presenter: Francesco Chiavaioli, National Research Council (CNR), Institute of Applied Physics "Nello Carrara" (IFAC)

Francesco Chiavaioli received the M.Sc. degree in telecommunications engineering and the Ph.D. degree in information engineering from the University of Siena, Italy, in 2008 and 2012, respectively. In 2015–2016, he spent six months as a Visiting Scientist with the Institute of Photonic Sciences (ICFO, Barcelona, Spain). From 2018, he is permanent researcher at CNR-IFAC. His research interests encompass optical biosensing platforms, fiber-optic sensors, optical resonances in guided-wave optics, whispering gallery mode resonators and novel photonic nanostructures. On the above topics, he has published more than 70 contributions among ISI journal, book chapters and conference proceedings. He has been involved in several international, bilateral and national projects. He is part of Editorial board of MDPI Optics and of SPIE Photonics Europe. He is Member of OSA, SPIE, ACS, EOS and SIOF. He was awarded as Outstanding Reviewer in 2018, 2019 and 2020 by IEEE, OSA and IOP, respectively.
