Editorial
Putting optics into focus In its most practical form, photonics isn’t such a complicated industry. It has three basic components: the generation, manipulation, and detection of light. As an industry, we invest most of our attention in the manipulation part, which enables, enhances, and bridges the industry’s other pillar practices. Without the ability to focus, diffract, reflect, transmit, or filter photons,...
