Five Common Design Mistakes Can Send PIC Packaging Costs Skyrocketing We have all heard that photonic integrated circuits (PICs) can pack a ton of functionality into high-performance, energy-efficient, and low-cost microchips, as well as the promise that they will enable a revolution of powerful optoelectronic devices for a host of applications. However, the complexity of transforming chips into functional devices is often underestimated and the cost of PIC...
Ultrashort-Pulsed Lasers Ramp Up the Power If lasers helped to redefine many manufacturing operations, then ultrashort-pulsed (USP) lasers promise to revolutionize them. They can process almost any material, and they can do so with a...
How to Preserve Your Laser Optics Against UV Degradation Ultraviolet laser optics tend to have limited lifetimes, due primarily to two processes: laser-induced contamination (LIC) and UV fatigue. LIC is caused by the deposition of unwanted material on the...
Chalcogenide Glass Sharpens the Outlook for Infrared Imaging Chalcogenide glasses — more commonly known as chalcogenides — have been around for some time and offer several benefits over other IR optical materials. They are comparatively lightweight, offer...
Manufacturing Methods Make Freeform Optics More Accessible From applications in ophthalmology, endoscopy, and microscopy — to use in head-up displays, lidar systems, unmanned aerial vehicles, and satellites — freeform optics are enhancing the...
Editorial
Ending scientific collaboration will not end risks Though the drift away from globalization has unfolded slowly during the past several years, it would be hard by now for anyone to miss the gap growing between the U.S. and China. Fueled by intellectual property disputes, trade wars, an apparent spy balloon, and increasingly stringent controls over exports and investments, the long-fraught commercial competition between the two countries looks...
