A New Generation of Femtosecond Lasers Packs Practicality with Precision To say that femtosecond laser technology has undergone a transformation in recent years is an understatement that not only minimizes the huge strides made in technical terms, but especially so the improvements in accessibility. Complex tabletops crowded with user-built assemblies and myriad discrete optics requiring daily attention have given way to single-box systems tailored to meet the...
Single-Photon Avalanche Diodes Sharpen Spatial and Temporal Resolution As their name implies, single-photon avalanche diodes (SPADs) detect single particles of light, and they do so with picosecond precision. Single-pixel SPADs have found wide use in astronomy, flow...
Raman Spectroscopy’s Signals and Future Continue to Get Brighter Spurred by the passage of state legislation last fall, the Southern California Coastal Water Research Project issued a methodology for monitoring microplastics in drinking water. The California...
Editorial
Pushing the boundaries of accuracy and precision Those who favor precise language should understand that precision does not mean the same thing as accuracy — at least not to folks for whom precision and accuracy are the stock-in-trade. In science and engineering, accuracy describes how closely a measurement conforms to the true value of the measured item. Precision is defined by how consistently repeated measurements arrive at the same...

Photonic Fundamentals
When Processing Battery Materials, Optimize Lasers for Safety and Quality Laser technology has become an increasingly vital tool in the production of batteries for electric vehicles (EVs). High-power laser tools are now commonly used to process materials at several steps during the production of EV batteries. Lasers cut anode and cathode materials. They clean electrolytes, dust, and other contaminants from parts before welding. And as coherent light sources, they are...

The Russia-Ukraine War Shifts Risks in Global Supply Chains and Markets The Russian military invasion of Ukraine on Feb. 24 activated a global narrative that could unfold over months and even years. While the eventual scale and outcome of the war remain open questions, the potential implications of the conflict are already rippling through global markets and supply chains, and many stakeholders in the photonics industry are scrambling to understand their exposure to...

Tunable Nanophotonic Interface Simplifies PIC Integration A chiral nanophotonic interface developed by a research team at the University of Chicago could make photonic integrated circuits (PICs) easier to integrate into mapping systems, biosensors, and other technologies. The interface provides a way for PICs to direct light at the nanoscale. PICs typically use optical isolators to control the direction of light. These devices prevent light from...
