Slow-light dissipative solitons in an atomic medium assisted by an incoherent pumping field
Nuno A. Silva, André L. Almeida, A. Guerreiro
This work models the propagation of an optical pulse in a 4-level atomic system in the electromagnetic induced transparency regime. By demonstrating that linear and nonlinear optic…

The role of local field modes in calculating the effective optical properties of metamaterials
Anderson O. Silva, Ivo T. Leite, José M. Teixeira +3
This letter discusses the importance of the nature of local fields inside a unit cell of optical metamaterials in developing a valid effective medium theory. In particular, we appl…
