Figure 3 | Electric field distributions over large-area zero-index PhC slabs with (a, c) and without (b, d) BICs. (IMAGE)
Caption
a-b, The PhC slab is excited by a plane wave incident from the left. Under the conditions of BICs, the incident light can propagate over a long distance with little loss. However, without BICs, the electric field decays sharply at the input end of the PhC slab. c-d, An electric dipole at the centre of the BIC zero-index PhC slab radiates omnidirectionally over a large area. However, an electric dipole in the centre of the zero-index PhC slab without BICs can only radiate over a small area.
