SPIE, the international society for optics and photonics’ Post

Optica’s Optics & Photonics News (OPN) Magazine recently featured ground-breaking research from the Nanophotonics & Metamaterials Group at the Optoelectronics Research Centre (ORC). The group is led by Professor Nikolay Zheludev, one of the founding figures in the field. Nanophotonics is concerned with the science of interactions between light and matter at the sub-micron scale. Over the past few decades, it has fundamentally impacted technologies including TV displays, medical diagnostics and treatments, and sensing. This OPN article explores the emergence of a new field: Picophotonics. Professor Kevin MacDonald, a member of the research group explained: “Picophotonics deals with light at a scale 1000 times smaller than the domain of nanophotonics. It is the science of light at the atomic scale. For context, the typical size of an atom is around two hundred picometres.” If you want to learn more, click on the link: https://lnkd.in/eEaDNqVv

Infrared nanoresonators harness the energy of IR for optics and electronics 🔬 Innovation Alert! Stanford University and Lawrence Berkeley Lab have developed cutting-edge nanoresonators harnessing the power of infrared light for optics and electronics. These tiny structures, made through a bottom-up self-assembly approach, promise a leap in performance for IR applications. 🌐 By using van der Waals materials and a novel flame vapor deposition process, researchers achieved ultrathin nanostructures that resonate strongly with IR frequencies, exhibiting superior quality and high performance. These nanoresonators open doors for advancements in subwavelength imaging, thermal emission systems, and molecular sensing. https://lnkd.in/diGDGQNf #Nanotechnology #Optoelectronics #Innovation #IRApplications Photonics Media

Erbium is commonly used in telecommunications devices and shows potential for applications in quantum communication. To scale up its use in larger #quantum networks, it needs to be easily integrated into current photonics devices.   🔗 https://lnkd.in/gwRwuiE6   In research supported by Q-NEXT, scientists at Argonne National Laboratory the University of Chicago grew thin films of erbium-doped titanium dioxide on silicon. The researchers developed a growth process that kept the film’s surface smooth, crucial for integrating with nanophotonic devices.   After connecting these structures to high-quality resonators, the team found that the structures were able emit photons for longer stretches of time. This shows that the group’s method for growing erbium-doped thin films allows them to be easily integrated with silicon photonics — and may be used for on-chip amplifiers, lasers, or quantum memories.   Learn more: https://lnkd.in/gwRwuiE6   #qnextresearch #quantuminformationscience #quantumscience #quantumengineering #quantummaterials Pritzker School of Molecular Engineering at the University of Chicago Center for Nanoscale Materials

🌟 Photonic Time Crystals Could Revolutionize Optics Faster Than We Can Explain 🌟 Researchers have just achieved the impossible: Photonic Time Crystals (PTCs) in the near-visible spectrum! This groundbreaking discovery is set to revolutionize the world of optics. Until now, PTCs were confined to radio waves, but a recent study published in Nanophotonics reveals that by rapidly modulating the refractive index, we can now create PTCs in the near-visible part of the spectrum. What's remarkable is that these PTCs are only stable when the refractive index matches the frequency of electromagnetic waves. This breakthrough was made possible by sending ultra-short pulses of laser light through transparent conductive oxide materials. The implications of this discovery are vast and could pave the way for disruptive applications in the science of light. Lead author Mordechai Segev and his team have opened a new chapter in optical science, and we can't wait to see what innovations await! 🚀 https://lnkd.in/gAcP53Q8 #Optics #Innovation #ScienceBreakthrough Technion - Israel Institute of Technology SciTechDaily

MSU Unveils Advanced Method for Identifying Defects in Semiconductors Physicists at Michigan State University have developed a ground breaking technique that combines high-resolution microscopy and ultrafast lasers to identify semiconductor defects with unprecedented precision. This method is effective in nanoscale components and allows for detailed observation of electron movement around atomic defects, significantly advancing semiconductor physics and opening new possibilities for materials like graphene. The technique described in Nature Photonics uses scanning tunneling microscopes (STMs) paired with terahertz laser light to detect single-atom defects in materials such as gallium arsenide. This breakthrough not only validates decades of theoretical research but also holds the potential to significantly boost the performance of future nanoscale electronic devices. #SemiconductorTechnology #Nanotechnology #HighResolutionMicroscopy #UltrafastLasers #MaterialsScience #PhysicsInnovation #GrapheneResearch #MSUResearch #WissenResearch
