Microelectrode arrays (MEAs) have diverse applications across a wide range of industries—including microelectromechanical systems (MEMS) for compact precision sensors, test devices for semiconductor chips, and energy storage solutions such as battery or fuel cell technologies. Notably, MEAs also play a crucial role in various medical applications, such as implantable sensors for cardiac electrophysiology, microneedles for […]

In this second installment of a two-part episode, Metalenz CEO Rob Devlin talks about what the future holds for the company and the industry overall, and offers some advice for others looking to take a similar path. Following the Photons: A Photonics Podcast dives deep into the fascinating world of photonics and optics. Join us

Lithium niobate is a leading material for integrated optics used in quantum and non-quantum optical applications. Due to its nonlinearity, it’s especially valuable when fabricating electro-optical devices for quantum state generation and manipulation. In particular, lithium niobate nonlinear waveguide networks—photonic structures based on the crystalline material—are uniquely suited for quantum state generation. To achieve a

This episode features Sargis Hakobyan, an R&D team leader with SPhotonix. He joined the company earlier this year to lead its new photonics lab in Switzerland, where he is the senior laser materials processing engineer. Sargis is a multilingual laser physicist who has long focused in solid-state femtosecond and semiconductor laser development. Following the Photons:

In a potential seismic shakeup for materials science, a team of researchers led by Zhifeng Ren, a physics professor and director of the Texas Center for Superconductivity at the University of Houston, recently overturned earlier theory work that predicted boron arsenide (BAs) can’t compete with the heat conduction of diamond. Thermal conductivity is a measure

Here's a look back at three articles covering work involving quantum entanglement, which Albert Einstein famously viewed as “spooky action at a distance.” Source link

In this episode of Photonics Hot List: A glasses-free, truly immersive experience could soon be possible. Researchers at Zhejiang University in China have designed a 3D display that touts significantly higher image resolution and a radically vivid depth display.  Business news roundup: Voyant Photonics, developer of on-chip frequency-modulated continuous-wave (FMCW) LiDAR systems, has announced the

Artificial intelligence is transforming every aspect of our digital economy, and its demands on infrastructure are unlike anything the semiconductor industry has encountered before. Data centers are straining under the weight of exponential growth in compute workloads and bandwidth requirements. Electrical interconnects, the backbone of current systems, are showing their limits in latency, heat, and

The HNDL threat crypto agility can’t address HNDL attacks pose existential threats to long-lived sensitive data. Adversaries intercept and store encrypted communications today, then decrypt them when quantum computers or cryptanalytic breakthroughs emerge years later. This isn’t theoretical—intelligence agencies have long pursued bulk data collection with precisely this strategy. PQC advocates invoke “crypto agility”—swapping cryptographic

For two decades, terahertz technology carried the promise of nondestructive, material-specific insights but remained primarily confined to research labs. The scientific community was impressed with demonstrations of nondestructive, label-free probing through polymers, coatings, and tablets, resolving structures on picosecond timescales, and detecting spectral fingerprints of water and other materials. But the systems were large, alignment-sensitive,
