Fig. 1. (a) Representation of microcavity modes excited by radiation (purple) incident at angle φ. The electric field polarization of the TE modes (red) lies along n[combining circumflex]q while that of TM has êq (blue) and êz (green, magnitude only) components. (b) Dispersion (energy as a function of mirror-plane wave vector q) of the photonic mode of index m in microcavity with transverse length L.
