In 2017, research analysts at UBS Securities disassembled a Chevy Bolt, the world’s first mass-market electric vehicle (EV), and a Volkswagen Golf, Europe’s top-selling internal combustion engine (ICE) car. When the UBS team compared the material compositions of the two vehicles, they unveiled one of the greatest emerging opportunities for photonics technologies in the automotive industry. Copper’s absorption of blue laser light is several times greater than its absorption of infrared light. Aluminum shows a similar, if smaller, response to blue light. As a result,...Read full article
