Loss-Compensation in 3D Periodic Arrays of Nanoshells through Quantum Dots, and epsilon-Near-Zero Metamaterials
Abstract
We compensate for the losses in 3D arrays of nanoshells through quantum dots embedded in the nanoshells' cores, to achieve ε-near-zero metamaterials at optical frequencies. Results show loss-compensation or gain-capability in a narrow frequency band. © OSA 2012.
