From: Interdisk spacing effect on resonant properties of Ge disk lattices on Si substrates

(a–c) Dependences of the reflection level in two minima at wavelengths ~ 400 and 800–900 nm on the G value for arrays with disks 90, 120 160 nm high, respectively. Ssub in (b) is the fraction of the surface not occupied by Ge disks.
