From: Resonant Tunneling in Photonic Double Quantum Well Heterostructures
Several transmission spectra from a PDQW heterostructure with constant outer barrier thickness (d B = 10L B ) and well width (d A = 10L A ), while the inter-well separation (d W ) is varied. The solid red curve, dashed blue curve, and dot-dashed black curve correspond to d W = 5L B , 10L B , and 20L B , respectively. When the photonic wells are close together, strong inter-well coupling enhances the energy-splitting effect. As the wells are separated, the interaction between degenerate states diminishes, and the energy splitting cannot be resolved
