Fig. 2: Features of various photonic modes in topologically curved microcavities.
From: Manipulating cavity photon dynamics by topologically curved space
a–h labels modes of different origins. a The frequency of modes a-h as a function of k. b The Q-factor of mode a (which is a 4-period island mode) as a function of k, showing a series of dips corresponding to the resonant point with other modes (labeled with the corresponding letters). c Light trajectories [left panels of (c–a) to (c–h)] and electric field spatial profiles [right panels of (c–a) to (c–h)] of modes a–h (top view). Each graph in c corresponds to the point in a pointed by the arrow with the associated letter
