“Figuring out how to shape this interaction without losingamplification was the real challenge,” said Eric Kittlaus, agraduate student in Rakich’s lab and the study’s first author.“With precise control over the light-sound interaction, we will beable to create devices with immediate practical uses, including newtypes of lasers.”



These opportunities have motivated numerous groups around theworld to explore such hybrid technologies on a silicon chip.However, progress was stifled because those devices weren’tefficient enough for practical applications. The Yale group liftedthis roadblock using new device designs that prevent light andsound from escaping the circuits.


Rakich said combining the two capabilities “is like giving aUPS driver an amphibious vehicle — you can find a much moreefficient route for delivery when traveling by land orwater.”


The prevalence of silicon chips in today’s technology makesthe new system particularly advantageous, the researchers note.“Silicon is the basis for practically all microchip technologies,”said Rakich, who is an assistant professor of applied physics andphysics at Yale. “The ability to combine both light and sound insilicon permits us to control and process information in new waysthat weren’t otherwise possible.”


In a study to be published in the journal Nature Potonics, ateam led by Peter Rakich describes a new waveguide system thatharnesses the ability to precisely control the interaction of lightand sound waves. This work solves a long-standing problem of how toutilize this interaction in a robust manner on a silicon chip asthe basis for powerful new signal-processing technologies.
