Li Ge’s Research on World’s Smallest Gyroscope Appears in Optica

Assistant Professor Li Ge (GC/Staten Island, Physics) has published a study in Optica that describes his development of what may help create the world’s smallest gyroscope.
 
Ge, working with research partners at Yale University, reduced an essential component of gyroscope technology to a fraction of a millimeter: a pair of light waves traveling in opposite directions around a microscopic cavity.

Gyroscopes are used by space probes, satellites and other navigation technologies to provide stability and maintain a reference direction.  
 
“We have found a new detection scheme that may lead to the world's smallest gyroscope,” Ge told The Optical Society, which publishes Optica as its flagship peer-reviewed journal. “Though these so-called optical gyroscopes are not new, our approach is remarkable both in its super-small size and potential sensitivity.”

This new approach eliminates the fundamental issue that prevented the miniaturization of optical gyroscopes in the past.
