Several members of our consortium will be participating in the SPIE Photonics West 2024 conference in San Francisco, United States, from January 27 to February 1.
This conference is a significant annual event for photonics research and technology, providing a forum for scientists and companies to present new research, showcase new solutions and component systems, explore emerging science, and foster collaborations.
Virginie Nazabal (University of Rennes), Petr Nemec (University of Pardubice), and Isaac Doughan (University of Eastern Finland) will present research on IBAIA’s photonic sensor modules through talks and a poster on Wednesday, January 31:
- Prof. Virginie Nazabal will give an invited talk from 10:50 to 11:20 AM PST at Moscone Center in Room 2012, on “Infrared photonic sensors based on chalcogenide thin films for monitoring of water pollutants”.
The presentation will focus on the development of a chalcogenide-based MIR platform dedicated to MIR spectroscopy with evanescent waves. This research is an important step towards the development of IBAIA’s optical sensor in the MIR spectral range that uses chalcogenide materials to detect organic molecules in water. - Soon after, Prof. Petr Nemec will give a talk from 2:10-2:30 PM PST at Moscone Center in Room 2022 on “Amorphous tellurite thin films prepared by sputtering.”
The talk will detail the fabrication and characterisation of erbium-doped tellurite thin films as part of the search for novel oxide materials for application in photonics sensors. The deposited films were thoroughly characterised using X-ray diffraction, atomic force microscopy, profilometry, transmission spectroscopy, variable angle spectroscopic ellipsometry, scanning electron microscopy with energy-dispersive X-ray analysis, and luminescence spectroscopy. The findings will be discussed in relation to the chemical composition of the thin films produced. - Last but not least, Mr Isaac Doughan, a brilliant final year doctoral researcher at UEF, will present a poster titled “Strip-loaded Mach-Zehnder interferometer for absolute refractive index sensing” from 6-8 PM PST at Moscone Center in Room 2003.
The poster will showcase the design, fabrication, and characterisation of a Mach Zehnder interferometer on a strip-loaded platform made of a Ti02 layer on an oxidised silicon wafer for liquid refractive index sensing. The novel design features a large (10 µm by 5 mm sensing length) opening in the sensing arm, resulting in a 23% cladding confinement factor. The design has an experimental homogeneous sensitivity of 0.128, which validates its unique efficacy.
If you’re attending the conference, we encourage you to check out the talks and the poster session to get insights into the recent work of the IBAIA team!
