Abstract

Exceptional points formed in a coupled optical microresonator structure with unbalanced decay rates are studied for dispersion engineering. Combined with oscillating coupling coefficients in the coupled-resonator architecture, periodic exceptional points are formed, providing additional degrees of freedom for narrow-band dispersion modification.
