Petermann-factor sensitivity limit near an exceptional point in a Brillouin ring laser gyroscope
Operating a laser gyroscope near an exceptional point has been shown to enhance its responsivity. However, here the authors demonstrate in theory and experiment that the enhanced responsivity is exactly compensated by increased noise that is inherent to this system near the exceptional point.
