Current spatial light modulator (SLM) technology offers off-the-shelf spatial phase control of light, but
amplitude control is much more limited. The development of amplitude-only modulators would enable devices
to perform full-wavefront control. Here we present an approach to the realization of such modulators, using a
phase-change material based approach. Fabricated devices allow for the control of the amplitude, with near zero
effect on the phase of the reflected wave, offering a potential route to ultra-fast, solid-state wavefront control.
