Normalized transmission spectra from \(\hbox {Alq}_{3}\) for \(N=3\) cavity devices with r = 1.0, 1.03, 1.06, 1.09, 1.12, and 1.15 in the center cavity. Shown here are the second (\(j=2\)) and third \(j=3\) bands of states. The three lowest energy states from the fundamental or first band (\(j=1\)) have wavelengths far longer than 800nm. The vertical dotted red line roughly at 691 nm and the dotted blue line at 483 nm indicate the centers of the photonic bands for the \(j=2\) and \(j=3\) states in a single microcavity with \(t_\mathrm{{org}}={t_\textrm{s}}\).
