Optical communications shrinks the planet Twenty-some years ago, during the heady days of the dot-com bubble, the optical networking industry was scrambling to lace the globe with optical fiber components to meet an anticipated explosion in bandwidth demand. The arguably irrational exuberance and speculation during this time made the Optical Fiber Conference (OFC) the most dazzling industry trade show to attend for an ingenuous new...

OFC 2023 Extends Its In-Person Format with a Hybrid Conference The 2023 Optical Fiber Communication Conference and Exhibition (OFC) returns to San Diego March 5-9, bringing a projected 12,000-plus attendees, 500-plus exhibitors, and dozens of cutting-edge technical sessions. This year’s in-person conference will be supported by a hybrid format to help extend its reach to a global audience. The live event’s multitude of displays and highlights...
Laser Safety
Visual Light Transmittance Is Not So Transparent Every user of laser protective eyewear is told to select his or her gear based on a limited number of factors. These might include the wavelengths the eyewear covers, its optical density/beam attenuation capabilities, its fit and angular coverage, and its visual light transmittance (VLT). The guiding principle for VLT is that laser protective eyewear should transmit enough light in the visible...

Mechanochromic is the new black Clothing has always used color to convey cultural identity, societal functions, or social standing. But, for centuries, fabric colors were subject to exacting mineral extractions and tortuous supply chains that consigned humanity’s limited palette to a lucky few. As a consequence, for much of our history, the evolution of color in clothing could be measured in eras. In fourth-century...
