Tiny Quantum Dot Sensors Solve Big IR Application Problems As a second quantum revolution begins, many mysteries remain in the quantum realm. Perhaps this is unsurprising given the notoriously confounding properties of this new frontier. However, as time passes, it seems increasingly likely that the development of new technological advancements and applications depends on understanding these mysteries. For example, quantum technology could enable a...
New Sensors and AI Optimize Laser Welding Welding is an ancient technology. Five thousand years ago, Egyptians used it to join copper water pipes together. Over the centuries it evolved into an essential technology to fuse various types of...
Increased Component Density Plants Hurdles on the Road to Scaling the Production of PICs When CEO Iñigo Artundo’s company began providing engineering solutions for photonic integration in 2011, the typical photonic integrated circuit (PIC) had five to 10 components. Today,...
Editorial
Wants, needs, and what lies between This is not the first time the global photonics industry has confronted supply chain disruptions, nor will it be the last. But the current wave of chaos might well be remembered among the worst and most persistent. It has affected the flow of many products along the photonics value chain, from neon gas to optical slurries, and it arises from a mind-bendingly complex web of factors that encompass...

Lasers fry roaches on the fly Roaches are notoriously hard to eradicate. Their ability to endure has made them emblematic of the last vestige of life that will survive an apocalyptic nuclear exchange. Humans, who like to be upstaged by insects even less than they enjoy finding them in the pantry, can therefore be excused for taking roach eradication to irrational and even dangerous extremes. Our species, for example, has long...
