Abstract
Significant suppression of radiation in 3D structured media with small refractive indices of 1.4–1.6, such as glass or polymers, is a desirable feature yet to be obtained. We present here quasiperiodic 3D structures with a homogeneous distribution of Bragg peaks on a sphere in reciprocal space obtained by an overlap of multiple gratings. 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 −10dB suppression of emission for a refractive index as low as 1.30.
