Abstract
We show that graded metallic gratings are capable of trapping electromagnetic waves at multiple frequencies within a certain band, manifesting itself as a trapped rainbow in the telecom frequency range. Thermo-optic material could be employed to make the structure to be temperature tunable. © 2009 OSA/ACP.
