Described herein are compositions that are photorefractive upon irradiation by multiple laser wavelengths across the visible light spectrum. Embodiments of the photorefractive composition comprise a polymer, a chromophore, and a sensitizer, wherein the polymer comprises a repeating unit including at least a moiety selected from the group consisting of the formulae (Ia), (Ib) and (Ic), as defined herein. The photorefractive composition can be used in optical devices. |
