    Abstract

    Outperforming conventional design concepts, a flat-top drop filter has been designed byapplying 3D topology optimization to a single waveguide-coupled L3 photonic crystal cavity.Measurements on the design fabricated in silicon-on-insulator material reveal that the pass-band ofthe drop channel is flat within 0.44 dB over a wavelength range of 9.7 nm with an insertion losslower than 0.85 dB.
