The geometric phase has acquired interest for optical devices such as achromatic phase shifters, spatial light modulators, frequency shifters, and planar lenses for wavefront engineering. Numerical work with Reusch piles with a large number of layers per period suggests that the geometric phase of the reflected/transmitted plane wave may be sensitive to nanoscale morphological differences, and the geometric-phase spectrum could contain signatures of morphological details that depend on the fabrication technique.

摘要

The geometric phase has acquired interest for optical devices such as achromatic phase shifters, spatial light modulators, frequency shifters, and planar lenses for wavefront engineering. Numerical work with Reusch piles with a large number of layers per period suggests that the geometric phase of the reflected/transmitted plane wave may be sensitive to nanoscale morphological differences, and the geometric-phase spectrum could contain signatures of morphological details that depend on the fabrication technique.
