More than four years ago, a groundbreaking study by Ulises Felix Rendon, Israel De Leon and Pierre Berini demonstrated through simulations that two surface plasmon waves could interfere in a gold nanoslit, creating distinct electrical field distributions depending on phase differences and the size of the slit. Inspired by this, I embarked on a journey to turn this concept into a real, ultra-sensitive biosensor for medical diagnostics. Throughout my PhD, I delved into numerical simulations, mask designs, and advanced nanofabrication techniques. Today, I'm thrilled to share that we have successfully demonstrated these modes experimentally. In this video I change the phase difference between Surface Plasmon Waves to go from a Dipolar mode to a Quadrupolar mode periodically. This achievement is a significant step toward developing a practical tool for impacting healthcare. As an engineer, it's my mission to create innovations that impact society positively. Looking at these modes is very promising, and having this technology already in hand is a big step forward. We hope this product can reach many and make a real difference in people's lives. #tecdemonterrey #uottawa #photonics #plasmonics #biosensor #interferometer

🚀 Exciting Advances in Photon Upconversion! 🚀 In a 2023 study, researchers explored the intriguing phenomenon of photon upconversion (UPC) in transition metal dichalcogenide (TMD) monolayers. This light-matter interaction process, where emitted photons have higher energy than incident ones, has vast potential in energy harvesting, biosensing, displays, lasers, and optical manipulation. The study highlights the unique properties of TMD monolayers, such as strong optical transition strength and phonon-exciton interaction, making them ideal for enhanced light-matter interaction. A Key tool used in this groundbreaking research included the ISS Q2 confocal laser scanning system. This system enabled precise confocal PL and UPC mapping, as well as fluorescence lifetime measurements, contributing to the comprehensive understanding of these phenomena. These findings pave the way for advanced applications in quantum light sources, artificial excitonic crystals, and high-performance semiconductor lasers.
