A new device can focus light into a point just a few nanometers across and may lead to next-generation applications in computing and imaging. Because light can carry greater amounts of data more efficiently than electrical signals traveling through copper wires, today’s technology is increasingly based on optics. The world is already connected by thousands of miles of optical-fiber cables that deliver email, images, and the latest video gone viral to your laptop.
