A light field generator system including a leaky-mode SAW modulator is disclosed. The modulator incorporates at least one optical power component, such as a concave mirror or volume grating having a non-zero diopter rating. In some embodiments, the system incorporates the at least one optical power component by embedding the optical power component within a substrate of the SAW modulator and/or by placing the optical power component upon a surface of the SAW modulator.
