Abstract
- The benefits of employing a quaternary phase-only hologram, programmed onto a silicon backplane Spatial Light Modulator (SLM) are evaluated with respect to insertion loss and crosstalk isolation between two single-mode fibre ports. It is shown that insertion loss for a binary phase hologram with current FLCs, is comparable to that of quaternary phase holograms utilising deformed-helix (DH) FLCs. Its worst-case crosstalk performance is no worse than that of a quaternary phase hologram for a typical regular fibre array design.
