Researchers have demonstrated a chip-scale Brillouin laser ring gyroscope that detects rotation as slow as 37 degrees per hour, a nearly 2,000-fold improvement over their previous integrated device.

Ring laser gyroscopes (RLGs) measure rotation via the Sagnac effect: a slight difference in the frequency of the two counter-propagating beams within the resonator ...
