Abstract
We report on the fabrication of form birefringent structures using 3D laser printing technique and describe optical properties of the fabricated samples. By employing 3D periodic structures instead of the simple 1D gratings that are typically used, we were able to realize mechanically robust form birefringent structures whose thickness and optical length of the birefringent region can be increased without loss of the mechanical stability, and achieve the quarter- and half-wave phase retardation levels needed in many applications. In the future, similar structures may become useful as the building blocks of polymeric photonic devices.
