Abstract
The generation of an autofocusing circular Airy beam (CAB) is realized via a liquid crystal (LC) geometric phase plate with a simple configuration. The fabrication of the LC plate is based on the photoalignment technology and dynamic exposure skill. A focal length of 74 cm is obtained, and the propagation dynamics are consistent with the simulations. Besides, a defocusing CAB is also generated, and the switch between the autofocusing and defocusing CABs can be achieved by controlling the input polarization state. This work provides a convenient and flexible approach to acquire CABs, which will promote the CAB-related applications and researches.
