We present a method based on the modal expansion approach for computing resonant modes of a high‐Q optical resonator. We reconstruct both the complex eigenfrequencies and the spatial modal profiles by solving an inhomogeneous linear system excited by a current source in the resonator. © 2014 Wiley Periodicals, Inc.
