In this paper, we develop a method to prepare a liquid crystal (LC) lens using photoalignment technology. It's fabricated by utilizing variable pretilt angles of a photoalignment layer. By irradiating a Gaussian profile laser beam on a photoalignment layer, variable angles from 1° to 89° are formed. In this way, the tunable LC concave lens with negative power is fabricated and characterized. It requires low voltage control for its tunable feature, which results in low power consumption. Such lens can play a great role in many modern optical and photonic applications.
