Specialized components that send and receive light signals across optical fibers are usually made from exotic crystals or semiconductor materials that are expensive and hard to work with. Now, researchers have unveiled a component that can do this light work but is made of silicon, the workhorse material of microelectronics. Because chip makers are already masters at handling silicon and the material is cheap, the advance could lead to inexpensive circuits that process light, scientists say.
