Freeform Optics and Metasurfaces Create Compact AR/VR Eyewear
A team from the University of Rochester’s Institute of Optics imprinted freeform optics with a metasurface, in a combination of optical technologies that charts a course for a new fabrication method for AR/VR glasses. The metasurface conformed to the freeform shape of the optics used in the work, which allowed the researchers to develop an optical component that they call a “metaform.”.

Ti:Sapphire Laser Sets Mark for Pulse Intensity
At the Center for Relativistic Laser Science (CoReLS, Institute for Basic Science in the Republic of Korea), researchers report they have achieved high-laser pulse intensity of over 1023 W/cm2. The intensity, the researchers said, is a record that is approximately 10× higher than that previously reported by a team at the University of Michigan in 2004.

Nanoflashlight Could Turn Mobile Devices into Powerful Biosensors
Researchers at MIT built a device that they describe as a “nanoscale flashlight” on a chip. Much like a spectrometer, the MIT team’s nanoflashlight shines a beam of light on a material, analyzes the light after it has passed through the material at several wavelengths, and captures the interactions of light with the material for each color.

.: Upcoming Webinars

Quantitative CMOS Imaging – qCMOS: The Dawn of a New Era
Wed, May 19, 2021 11:00 AM - 12:00 PM EDT
Imaging in general and semiconductor imaging in particular has penetrated every aspect of our lives, especially in the sciences. It has empowered many experiments from relying on subjective recording into objectively documentable, repeatable and quantifiable methods. This webinar with Peter Seitz, Ph.D., will provide an overview of semiconductor image sensors and introduce photon-resolving quantitative imaging, or qCMOS. Presented by Hamamatsu Corporation.

Measuring the Power and Beam Profile of Divergent Laser Sources
Thu, May 20, 2021 1:00 PM - 2:00 PM EDT
Lasers with large beam divergence are used in a number of applications, such as remote sensing, optical communications, and materials processing. In this webinar, Derrick Peterman, Ph.D., will discuss methods for reliably characterizing the beam power and profile of divergent sources, so that users will be able to better understand how their lasers are performing in critical applications. Presented by Ophir, an MKS Instruments company.

.: All Things Photonics

Claudio Mazzali, CTO and senior vice president of technology at Corning Optical Communications, is our guest. The 2020 elected fellow of The Optical Society (OSA) guides listeners through an unprecedented 15-month period for optical technology, and shares his thoughts on what to expect from large-scale organizations such as OSA as they reemerge from the pandemic. Trends for a bright future in nanomaterials, hollow- and novel-core fibers, and optical fibers conclude the episode.
