One of the reasons I like to use LinkedIn is that one can come across to excellent pieces of information, like the Photonics Infographics (https://lnkd.in/d-bnk7G4) by SPECTARIS , just by browsing one's feed and checking what other people have felt worthwhile of sharing. The booklet provides common-sense explanations and examples of what photonics is, in a concise and enjoyable manner. #Photonics is not yet as recognizable industry as #electronics, so it's great to have such material available, to help us make our work known also for the general public, and not just for the field experts.

A University of Rochester research team proposes strategies to avoid contrast degradation in chirped-pulse amplification stretcher optics: https://ow.ly/POfn50Sh7oI Published in Applied Optics [#OPG_AO], the study also exploits computer numerically controlled polishing techniques to enhance surface figure and roughness on stretcher mirrors. The researchers indicate an advantage of using an Offner stretcher with cylindrical mirrors, where focusing in only one direction causes phase noise from the secondary mirror to be spread off axis in a high-intensity focal spot to increase the contrast ratio.

Scientists from CNR Nanotec in Lecce and the Faculty of Physics at the University of Warsaw used a new generation of semiconductor photonic gratings to optically tailor complexes of quantum droplets of light that became bound together into macroscopic coherent states. The research underpins a new method to simulate and explore interactions between artificial atoms in a highly reconfigurable manner, using optics. The results have been published in the prestigious journal “Nature Physics” #nanotechnology #quantum #materialsscience #optics #semiconductor #photonics #technology

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

📢 We are excited to introduce our next Topical Meeting at EOSAM 2024: TOM8 - Nonlinear and Quantum Optics Nonlinear and quantum effects in optical systems play a prominent role in many fundamental physics discoveries as well as emerging technologies. This topical meeting brings together leading researchers working in the field of nonlinear and quantum optics to discuss recent achievements and new directions. This TOM covers phenomena of both fundamental and technological relevance, as well as aspects of various systems (e.g., cavities, waveguides, interferometers, molecules, quantum wells/dots, etc.) where such phenomena arise. Topics discussed in this TOM include, but are not limited to: nonlinear dynamics from ultrafast to ultraslow time scales, novel materials and platforms for nonlinear and/or quantum optics, generation and manipulation of nonclassical states of light, frequency conversion, optical switching, effects of quantum and classical noise, parametric processes, classical or quantum sensing with nonlinear optical systems, non-Hermitian and topological physics in nonlinear systems, photonic quantum simulators, quantum transducers, integrated systems for quantum photonics, and nonlinear/quantum metasurfaces. Invited speakers in this TOM: - Juan Sebastian Totero Gongora: Gain-controlled nonlinearities and interactions for complexity-driven photonic reservoir computing - Karolina Slowik: Light interactions with polar quantum systems - Hui Cao: Spatiotemporal dynamics of semiconductor microcavity lasers More information: https://lnkd.in/dM5-Z4Vf Secure your spot now! 🗓️ Early Bird Deadline: July 8, 2024 🔗 Registration Link: https://lnkd.in/dGTACket #NonlinearandQuantumOptics #Photonics #Optics #Conference #Naples #EOSAM2024

Luying Yi, Xiaogang Liu and colleagues introduce an imaging technique named “stochastic photoluminescence and compressed encoding,” or SPACE. SPACE leverages randomly arrayed lanthanide transducers as photonic encoders to capture various excitation wavelengths in a single image, recorded by a charge-coupled device. This approach enables the reconstruction of multiple scenes from this encoded image across four wavelength channels: X-rays (0.089 nm), ultraviolet (375 nm), and two near-infrared bands (808 and 1,532 nm), with the ability to expand to more channels through multi-layer encoders. SPACE enables multi-channel imaging for depth visualization and multi-spectral X-ray analysis, offering broad multi-spectral sensitivity and on-chip compatibility. This makes it a versatile tool for applications in materials characterization, bioimaging, remote sensing, and astronomy. Online now in #Matter https://lnkd.in/eiZwsSRb
