Abstract
An all-polymer grating microstructure device that exhibits a zero-order reflection under white light comprises a first polymer having a first refractive index and configured as a microstructure embedded within a second polymer having a second refractive index, each of the polymers of the first and second polymers at least translucent to white light with the proviso that the refractive index of the first polymer is at least 0.05 greater than the refractive index of the second polymer.
