Yale scientists have created a new type of silicon laser that uses sound waves to amplify light. A study about the discovery appears in the online edition of the journal Science.
In recent years, there has been increasing interest in translating optical technologies — such as fiber optics and free-space lasers — into tiny optical or “photonic” integrated circuits. Using light rather than electricity for integrated circuits permits sending and processing information at speeds that would be impossible with conventional electronics. Researchers say silicon photonics — optical circuits based on silicon chips — are one of the leading platforms for such technologies, thanks to their compatibility with existing microelectronics.
