Abstract
We report a simple method for fabricating Pancharatnam-Berry micro-optical elements based on relayed Mach-Zehnder interferometer. Two major advantages are fast processing speed and good quality phase profile. Both active and passive micro-lens arrays are fabricated and their imaging performances characterized. To demonstrate the versatility of the proposed method, we also fabricated asymmetric, axial-symmetric, and concentric types of micro-lens arrays.
