Highlighted in OPN's #OpticsIn2025: Researchers achieved ultra-broadband frequency combs in two UV spectral regions: 372–410 nm, spanning 80 THz with 1,000,000 comb lines, and 325–342 nm, spanning 44 THz with 550,000 comb lines. https://t.co/GLjSbgG6m0

Every day in December starting tomorrow, OPN will highlight one of 30 exciting peer-reviewed optics studies published in the past year. Take a look at the #OpticsIn2025 hashtag to follow along and the link below to get a sneak peek! https://t.co/9XsEEIau7V

Image of the Week: Artistic Glassware Through creative use of artificial light, three water-filled glasses placed on a reflective surface against a dual-color background. [2025 #OPNPhotoContestWinner ] Read more here: https://t.co/hY0kMfXyqW

Image of the Week: Optical Mosaic Oil droplets dispersed in water create a beautiful natural mosaic. Each droplet acts as a tiny lens, bending and shaping the light into unique patterns. [2025 #OPNPhotoContest Editors’ Choice] Read more here: https://t.co/hY0kMfXyqW

Researchers have developed micrometer-scale micromotors that glide through the air on convection currents and could one day be used for gas-phase heterogeneous catalysis, aerosol toxin detection and pollution control. Read the OPN story: https://t.co/3eO7lTk7HG

Silicon nitride is actively shaping the future of #quantum devices, from single photons to supercooled atoms. Checkout the OPN feature article "Silicon Nitride: From Workhorse to Superstar" to learn more about the #material's unique properties. https://t.co/5oze9Vbhy4

Image of the Week: Atmospheric Palette At twilight, sunlight grazing the horizon is sculpted by Rayleigh scattering of the shorter-wavelength blue light and Mie scattering from larger particles and clouds. Read more here: https://t.co/hY0kMfXyqW

The company @ipgphotonics announced the opening of a new customer center and production site in Huntsville, AL, USA, that will serve as the headquarters of its newly created IPG Defense business. Read the OPN story for more: https://t.co/Z5Woy7MIC4

The OPN November Issue's feature article "FELs and the Future of Lithography" discusses how free-electron lasers may address today’s lithography bottlenecks and provide a clear path toward sub-nanometer nodes. Read the story: https://t.co/N2kTkFc29M #Lithography #Lasers #FEL

A new imaging method, called computational scattered light imaging, can quickly map tissue without specialized equipment! All someone needs is a rotating LED lamp and a standard microscope camera. Read the OPN story for more! https://t.co/J29ktiWbzJ #microscopy #imaging

In new work, researchers simulated a new material dupped "gyromorph" that should be able to block light in all directions. The material's unique properties could be leveraged to one day guide light through optical computers. Read the OPN story: https://t.co/QNz0267PFa

“We want to change things dramatically, not provide incremental improvements.” OPN spoke with Alexandra Boltasseva about her work in tailorable and tunable materials and the potential for interdisciplinary collaborations. Read the interview: https://t.co/iJnAKU8IUN

A new approach to spectral shaping extends spectral control to 10,000 individual comb lines and could assist in the hunt for Earth-like exoplanets! Read the OPN story: https://t.co/ePmon40IrD #exoplanet #laser #photonics

A new technique combines lasers, fluorescent dyes and artificial intelligence to "tag" cells with abnormal chromosomes that may become cancerous. Read the OPN story for more! https://t.co/8C8W7bYsCL
