Nvidia Details Plans to use Silicon Photonics to Scale AI Factories

NVIDIA announced plans to adopt silicon photonics and co-packaged optics to scale its AI architecture. Scientists led by Tobias Kippenberg have developed a photonic-chip-based traveling-wave parametric amplifier for communication networks. Marine technology company, Kraken Robotics, is acquiring 3D at Depth. Rocket Lab USA, a provider of launch services and space systems, is entering into an agreement to acquire a controlling position in Mynaric. ASML and imec are partnering to advance their research and sustainability. Hamamatsu Photonics has just completed construction on a new factory in South Korea. And Intel has named Lip-Bu Tan as its new CEO. Sponsored by LaCroix Precision Optics.

Ultra-Broadband Photonic Chip Boosts Optical Signals

Researchers led by Tobias Kippenberg at Ecole Polytechnique Fédérale de Lausanne and Paul Seidler at IBM Research Europe – Zurich have developed a photonic-chip-based traveling-wave parametric amplifier that achieves ultra-broadband signal amplification in an unprecedentedly compact form. The new amplifier attains a net gain of over 10 dB across a bandwidth of approximately 140 nm — three times wider than a conventional C-band EDFA.  Read Article

THz Spintronics Could Enable Ultrafast Readout of Magnetic Drives

The data storage capacity of multi-terabyte hard drives is several million megabytes, but their data transfer rates are only a few hundred megabytes per second, due to their reliance on tiny magnetic structures. The development of memory devices that operate at picosecond timescales could speed data transfer and improve access to digital information. However, ultrafast control of magnetization states in magnetically ordered systems is a challenge.  Read Article

Introduction to Imaging Radiometry and FLIR Research Studio
Introduction to Imaging Radiometry and FLIR Research Studio

Thu, Mar 27, 2025 11:00 AM - 12:00 PM EDT
Discover the fascinating world of infrared imaging radiometry! Infrared imaging radiometry involves using an infrared camera to measure the infrared radiation emitted by objects in a scene. Each pixel in an image captured by a radiometrically calibrated camera provides quantitative data. These radiometric images are not just pictures; they are 2D grids of infrared radiation measurements from the scene, typically displayed as temperature per pixel in most commercial applications. During this webinar, Matthew Hasty will explore the fundamentals of infrared technology, how it works, and the various sensor technologies available. The presentation will also touch on radiometric calibration for temperature per pixel. Finally, Hasty will demonstrate how software, particularly FLIR Research Studio, can enhance efficiency and drive scientific discovery for global teams in innovative ways.

Placing “Test” on the Integrated Photonics Value Chain — With Iñigo Artundo

Iñigo Artundo, CEO of photonic test and design house VLC Photonics, breaks down the function of test as it relates to PICs and integrated photonics. How developers advance chip and wafer architectures through the design stage and toward productization cannot happen without adequate testing. But the sophistication of current and future designs does not always align with established test protocols. This episode explores that dynamic and discusses how the gap can be bridged.
