Abstract

We numerically study several metasurfaces which include ferro-electric material, such as lithium niobate (LN) and explore their ability to control the phase, amplitude and polarisation of light. For each of these parameters, ideally we would like to be able to control them independently, without affecting others. We study metasurfaces containing silicon resonators on LN substrates as well as the patterned LN metasurfaces. We find that the amplitude and polarisation modulation are relatively easy to achieve in a single metasurface, however the best phase modulation we were able to achieve is approximately 70 degrees, in a metasurface which maintains high transmission amplitude at over 90%.
