It is well known that gratings with high spatial frequency (spacings ≤ λ/2) show form birefringence. Therefore, gratings formed in dielectric materials can act as a wave plate when the grating spacing is smaller than, or near to, half of the incident beam wavelength. Previous researchers used high frequency surface relief structures or sinusoidal gratings formed in photoresists to produce this effect. In this paper we show the performance of a volume holographic quarterwave plate formed in DCG operating at 632.8 nm. To our knowledge this is the first demonstration of a retardation plate exhibiting this magnitude of phase delay in a volume material. The fabrication techniques required to realize this element are also presented.
