An optically active structure ( 100 ) is provided, comprising at least two different groups (G 1, G 2 ) of optically active nanorods ( 104 A, 104 B). The groups of nanorods differ from one another in at least one of wavelength and polarization of light emitted thereby in response to pumping light. The nanorods of the same group are homogeneously aligned with a certain axis of alignment being substantially parallel or substantially perpendicular to an axis of alignment of the nanorods of at least one other group, such that the nanorods of said at least two groups have one or two axes of alignment. The optically active structure is used as colour polarized light source for displays. |
