Figure 2From: Coupled nanowire-based hybrid plasmonic nanocavities on thin substratesCross-sectional modal profiles. Field magnitudes |E(ρ)| for the fundamental hybrid plasmonic mode on thick substrates (t=500 nm), at a fixed rGaN= 40 nm and different rAg=(a) 20 nm, (b) 50 nm and (c) 120 nm. (d), (e), and (f) are the counterparts of (a), (b), and (c) for thin substrates (t=5 nm).Back to article page
