Direct electron beam patterning of diffractive structures in PEPC-SY3 azopolymer films

Abstract

Azopolymers are well known for their ability to record holographic gratings due to photoinduced molecular reorientation and mass transport processes occurring under polarized light irradiation. In particular, the azopolymer PEPC-SY3 exhibits pronounced photoinduced anisotropy, which enables efficient recording of polarization-dependent holographic structures. These unique properties make azopolymers promising materials for the fabrication of diffractive optical elements and polarization-sensitive photonic structures.
