Global Vision Lectures is initiated by the International Office of WUT. It aims to unite academic and research units to organize high-level academic lecture series, providing a high-quality, multidisciplinary international academic exchange platform for the university's faculty and students. This platform is designed to promote research collaboration, broaden international horizons, and further enhance the internationalization capabilities of both faculty and students. The sixth lecture will be held on Wednesday, October 18th. The information is as follows:

Topic 1: Printed nanowires-based photodetectors on flexible substrates

Lecturer: Professor Ravinder Dahiya

Time: October 18, 2023 (9:30am), UTC+8

Venue: Conference Center 104, Mafangshan West Campus

Organizer: National Engineering Research Center of Fiber Optic Sensing and Network Technology

Biography: 

Ravinder Dahiya is a professor in the Department of Electrical and Computer Engineering at Northeastern University. He is a Fellow of the Institute of Electrical and Electronics Engineers (IEEE), a fellow of the Royal Society of Edinburgh, the Chair of the IEEE Sensors Council, and the founder and inaugural editor-in-chief of NPJ Flexible Electronics. He has published over 500 papers, books, or patent applications.

Abstract: 

Semiconducting nanostructures such as nanowires (NWs) and Nanoribbons (NRs) have attracted significant attention for various sensors owing to their attractive physical and optical properties. Printed electronics route is particularly attractive because of resource efficiency and the potential for next generation of sustainable electronics manufacturing. This talk will focus on nanostructures-based printed electronic layers on different types of substrates and their further processing to develop various types of photodetectors on flexible substrates, and present different routes for semiconducting nanowire growth, methods for printed electronics layers, and fabrication of photodetectors.

Topic 2: Fiber optic sensors using lossy mode resonances

Lecturer: Professor Ignacio R.Matias

Time: October 18, 2023 (10:30am), UTC+8

Venue: Conference Center 104, Mafangshan West Campus

Organizer: National Engineering Research Center of Fiber Optic Sensing and Network Technology

Biography:

Professor Ignacio R. Matias is a fellow of the Institute of Electrical and Electronics Engineers (IEEE) and a professor in the Department of Electrical, Electronic, and Communication Engineering at the Public University of Navarre in Spain. He served as the Dean of the School of Computer Science and Telecommunications Engineering and the founding director of the Institute of Smart Cities from 2009 to 2014. In 2017, he took on the role of project leader for the Electronic and Communication Technology (TEC) project at the Spanish State Research Agency (AEI). Currently, he is the Chairman of the Committee for Spanish National Agency for Quality Assessment and Accreditation (ANECA). He has authored over 250 papers in international journals, written 7 specialized books, and contributed 21 chapters to various publications.

Abstract:

A lossy mode resonance (LMR) in optical fibers occurs when guided modes shift to a thin film on the waveguide due to specific material and angle conditions. LMRs uniquely guide both magnetic (TM) and electrical (TE) polarized light.

This talk will present the main milestones obtained during more than a decade using LMR-based sensors for the detection of multiple parameters, like detection of VOCs, humidity, biosensing, etc.. Among these interesting aspects, we can mention the sensitivity records achieved, hybridization with other sensing technologies or the possibility of multiplexing multiple sensors on the same substrate, just to mention a few.
