Swave Photonics, a developer of holographic extended reality technology, has raised €27 million ($28.27 million) in a series A funding round. The investment is expected to expedite the development of Swave's holographic extended reality (HXR) platform for AI-powered AR smartglasses and head-up displays.

Swave’s diffractive optics-based HXR technology enables 3D high-resolution images that adapt to the user’s surroundings. The company’s DynamicDepth technology allows the images to be processed naturally by the human vision system, bypassing AR’s commonly faced challenges of focal depth and eye-tracking.
Swave Photonics introduced its Holographic eXtended Reality platform in April 2024. The technology is...

Monitoring electrical signals in biological systems helps scientists understand how cells communicate, which can aid in the diagnosis and treatment of conditions like arrhythmia and Alzheimer’s.

But devices that record electrical signals in cell cultures and other liquid environments often use wires to connect each electrode on the device to its respective amplifier. Because only so many wires can be connected to the device, this restricts the number of recording sites, limiting the information that can be collected from cells.

Researchers at MIT have developed a biosensing technique that eliminates the need for wires. Instead, tiny wireless antennas use light to detect minute electrical signals.

As it relates to semiconductor and electronics manufacturing, miniaturization seems to have no limits. A simple examination of the components and even many of the finished devices fabricated in today’s manufacturing environments makes it easy to perceive this trend.

Yet despite the ubiquity of miniaturization in modern manufacturing, the processes and technologies necessary to fabricate nanostructures present dynamic challenges. Manufacturers supporting the semiconductor and consumer electronics industries have overcome many constraints on the road to sustainable miniaturization, or scaling, as it is known in the semiconductor industry.

In recent years, quantum computers have made headlines, while quantum communication solutions have made it to markets. Simple solutions, such as quantum random number generators, have been transferred into smartphones. Similar quantum encryption modules for terrestrial telecom router systems are available off-the-shelf.

The integration of photonic devices at the wafer scale has emerged as a transformative force, offering a reliable and scalable pathway to implement complex photonic functions cost-effectively on a chip. While integrated photonics has long been synonymous with optical communications, today’s landscape presents unprecedented challenges and opportunities — including those that fall outside the bounds of traditional optical telecommunications and data communications. As data volumes surge across growth sectors, the industry faces mounting pressure to deliver faster, more energy-efficient solutions and continuously improve the price-performance ratio.

The relentless expansion of data communication, propelled by advancements in artificial intelligence (AI) and machine learning workloads, as well as cloud computing, cloud storage, AR/VR, video on demand, 5G technology, the Internet of Things, and autonomous vehicles, demands a substantial increase in bandwidth. Hyperscale data centers are under continuous pressure to enhance and augment their network capacity. This is achieved through hardware upgrades, including more advanced switches, routers, and servers, which offer higher bandwidth via increased port speeds and higher port counts relative to previous generations.

In parallel, the optical interconnects that link these network devices must also...

To produce faux marble kitchen countertops, a manufacturer places a piece of solarized polypropylene — a thermoplastic polymer material — on top of white stone. To ensure that a successful bond is created, the stone must contact the nonsolarized side of the polypropylene.

The challenge: The visible eye cannot differentiate which side is which.

Laser microprocessing has been on the rise for decades. While technological roadblocks have influenced this progression, a close look at these roadblocks reveals that each has advanced to maturity. Productivity is key, and laser sources, scanners, and systems technology have made extensive progress; they are already used in large-scale applications, and much more growth is expected.

Laser sources and scanners

In the 1990s, scientists found that laser pulses in the pico- and femtosecond regime could be used to cut and drill almost any material with significantly reduced heat-affected zones and smoother walls compared with nanosecond pulses. Evidently, these ultrashort pulses (USPs) were well suited...

Mines are inherently challenging places to work, but even within such an environment, certain tasks are considered particularly risky. In the aftermath of a blasting operation, for example, miners must assess the resulting opening in the rock and determine whether valuable ore can be recovered or whether additional excavation is needed.

The traditional method that miners have used to perform these critical functions puts them in a precarious position. “They were actually sticking a laser scanner on a pole into these cavities,” said Brandon Duick, CTO at Exyn Technologies. “It’s not the safest thing to have engineers or surveyors have to get that close to the space where there could potentially still be falling...
