The broadband response of the metasurface covers S, C, and L telecommunication bands.This work has been supported by the Liverhulme Visiting Professorship, Engineering and Physical Science Research Council (EPSRC) under grant number EP/L000091/1 (PEACE), and EC 7th Framework Programme through Grants 627545 (SOLAS), 659950 (INVENTION) and 654809 (HSPACE).application/pdfen-AU© 2018 OSAMultiplexingOptical fiber communicationBroadband communicationModulationQ-factorDielectricsPhotonics20182019-11-25
