We mitigate off-chip radiation loss by enforcing the single beam condition by using metamaterial index engineering. The fabricated device exhibits insertion loss as low as 1dB and crosstalk lower than -25 dB. eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional Telecomunicaciones - Congresos Low-loss curved waveguide grating wavelength demultiplexer conference output
