Menhir Photonics’ Post

I will be heading to Frankfurt, Germany, this Saturday for #ECOC2024, the 50th European Conference on Optical Communication! I'll be speaking at SC08 on Wednesday, September 25th, at 16:00, on the topic of "Sensing and Microwave Photonics." My presentation will focus on "Machine Learning Driven Earthquake Early Warning Using Optical Fiber Mesh Networks," where I'll discuss how optical networks can be used to early detect earthquakes and pinpoint their epicenters through polarization changes in traffic-carrying optical fibers. Our results demonstrate a valuable time window for taking countermeasures: 27 seconds for urban areas within 20 km range, 37 seconds within 40 km, and almost 60 seconds within 60 km. Looking forward to sharing insights and connecting with fellow professionals! #ECOC2024 #OpticalCommunication #MicrowavePhotonics #MachineLearning #EarthquakeEarlyWarning #OpticalFiberNetworks #Photonics #SensingTechnology #Innovation #Research #Frankfurt #Networking #TechConference

A sneak peek into Photonics Finland member ElFys 4-Quadrant Detector ElFys is set to revolutionize the field of near-infrared (NIR) detection with the upcoming launch of its innovative 4-quadrant detector in January 2025. By applying the cutting-edge approach to a quadrant detector design, ElFys has created a detector that combines high responsivity, low dark current, and fast response times with precise positional information.

The XI International Symposium "Ultrafast Dynamics and Ultrafast Bandgap Photonics" is being held this week in the beautiful island of Crete, for the third year in a row, https://lnkd.in/eSrSfeKS I had the honor to start the conference with a plenary talk on how two-dimensional coherent nonlinear spectroscopy of superconductors allows for quantum tomography of light-controlled non-equilibrium states, with new breakthrough results, obtained in collaboration with Jigang Wang's experimental group at Ames Lab, on how a pulse-pair of intense Terahertz laser fields with controllable relative phase can image and induce light-controlled superconductivity. Having observed and controlled with a pulse-pair interference of different superconductor excitations, is room temperature light-induced superconductivity next?

Today is DAY OF PHOTONICS. A full day of celebrating and focusing on the fantastic world of photonics. Photonics is the physical science of light waves. It deals with the science behind the generation, detection, and manipulation of light - a technology tackling challenges in medicine, smart life, agriculture, defense, space exploration and many more areas. If you are seeking more information on photonics and how it can assist your business and industry, we recommend that you visit EPIC - EUROPEAN PHOTONICS INDUSTRY CONSORTIUM where plenty of information is available: https://lnkd.in/dMGcsk_K #sensors #photonics #opticalfiber #measuringwithlight #measurements #technology #innovation #fiber #predictive #engineers #development #linkedin

Attosecond laser pulses are so incredibly short that they let us measure the motion of electrons! Imagine trying to take a photo of a hummingbird in the air. It's wings are probably blurry because your camera's frame rate is slower than the speed of the wings Attosecond laser pulses essentially fix this issue when it comes to measuring fundamental processes But my favorite, mind-blowing fact is that the ratio of 1 attosecond to 1 second is the same as the ratio of 1 second to the age of the known universe! So that fact that laser pulses can be made that short is incredible This great infographic comes from the Photonics Infographics book created by SPECTARIS The English version of the book is available as a free download from SPIE, the international society for optics and photonics: https://lnkd.in/ebTN7yrt And SPECTARIS has interactive versions of these infographics here: https://lnkd.in/eT-aq7y7 #Optics #Lasers #Photonics
