Abstract
The design of diffractive phase elements with polarization selectivity was presented, which can realize polarization demultiplexing and spatial focusing simultaneously. The design scheme is based on the general theory of amplitude-phase retrieval and Y-G iterative algorithm. A set of equations for determining the modulation depth distribution of the surface-relief diffractive phase elements was derived. Two design examples were given. The numerical simulations show that this suggested approach can achieve the design of desired pattern.
