Abstract :
We have demonstrated the zero dispersion quarter wave plates in visible frequency range. The quarter wave plates were produced by using the subwavelength-period gratings to form the birefringence film. Taking this feature, we can design quarter wave plates for use in wide frequency range by the effective medium theory (EMT).
