Abstract:We experimentally show that the mode splitting in two-evanescently coupled Photonic Crystal L3 cavities (three holes missing in the K direction of the underlying triangular lattice) can be controlled through barrier engineering. The "potential barrier" is formed by the air-holes in between the two cavities. By changing the hole radius of the central row in the barrier up to ~30%, the frequency splitting can be strongly reduced. Moreover, the sign of the splitting can be reversed in such a way that the fundame… Show more
