Simulations on 3D structures revealed a limitation of emission suppression contrasting from theoretical predictions. The effect of number of gratings and refractive index contrast on the obtained suppression is investigated.We demonstrate an almost refractive index independent-10 dB suppression of emission for a refractive index as low as 1.30.en0740-322420234900904Journal Article10.1364/JOSAB.477576Other
