Phys.Org (Isle of Man, March 9) -- Light and electrons interact in a complex dance within fiber optic devices. A new study by Illinois engineers found that in the transistor laser, a device for next-generation high-speed computing, the light and electrons spur one another on to faster switching speeds than any devices available.
